Technical Field

The present invention relates to the lateral distribution of loads in super high- rise buildings using peripheral arms in order to reduce the effect of wind, earthquakes and explosions as well as increasing the utilized area. This is done by the construction of super high-rise buildings of regular or irregular cross- section along with the construction of a group of a tilted and outwardly curved peripheral arms of a feather shape around building corners. Then, tying these arms from the middle to building corners and from edges to each other from multiple tying points along building height using steel wire cables.

Background Art

The civilized development in many countries of the world, especially in recent decades has led to a concentration of population in urban areas, the numbers of the population in these areas in a steady increase that many problems had arisen in a particular shortage of available land. Although many opposing opinions to build high-rise buildings, but that the solution to the problem of population growth with land shortage by building such buildings which are called the vertical space, and who helps there in the rapid technological development leading to contribute to the rapid development of these communities and to absorb these increases and improving living conditions for them. There are also two reasons pushing many countries of the world for the construction of high buildings. First, the high-rise buildings leave trace of civilization alive in souls, therefore, competition has increased among themselves to build larger and higher buildings as a symbol of glory and prestige. Secondly, the tendency to use all what technology offers from inventions, which make them fail to curb the desires to use the technology allows to get high up more and more, as long as human nature has prompted us to use all tools.

But the problems that impede the further rise buildings of a certain extent in many countries due to the impact on high-rise buildings largely by winds and earthquakes in such a manner of possibility to be exposed to risk that requires an increase in the strength and rigidity of these buildings and the existence of a system for the prevention of such disasters which confirm the safety of such buildings against risks. Also the safety of high-rise buildings is now a nightmare, especially government buildings and buildings of national character, after bombing attacks on Alfred P. Murrah federal building on April 19, 1995, and the two towers of the World Trade Centre on September 11 , 2001, and which these deadly explosions had warned the world with the threat of terrorism. These buildings with the surrounding areas accommodate tens of thousands of people, which has made this high-rise source of danger and has led to an increase in the desire to secure these high-rise buildings against all of these risks so that it does not become a trap for the lives of thousands.

- Technical Problem

Problems and shortcomings in modern techniques used in the construction of high-rise building, which have been reviewed respectively are as follows:

a- Because all high-rise buildings swing with the wind, while the connection between buildings is not flexible with this swing will lead to the destruction of these connections and causing damage to buildings, and also the scarcity of the need to build a group of ultra-high buildings in the same form and at the same time so the best to design a protection for each building by itself,

b- Vibrations damping devices installation and maintenance so expensive and when a malfunction into it can lead to a disaster in case of exposure to hurricanes or earthquakes. Also the efficiency of the operation of this device after many years is doubtful, and should be checked after every earthquake to replace defected devices, since the activation of these devices happened with building swing this will make the inhabitants feels uncomfortable. For patent application JP111 17568 the design form has not been raised in the case of high-rise buildings, and the presented design for slender building with huge foundation is considered a waste of space. For patent application JP2001073585 the reinforcing frames must be a failure points in the case of devastating earthquake to protect the building and thus make it easy to be replaced. And for patent application US201 10271606 the decreasing area of the upper floors is considered a waste of space. c- The rigid structure doesn't flexibly deal with earthquakes, but depends on its rigidity when facing earthquakes, and the actual space used is very small relative to the total building area.

d- Building vibrations in the case of earthquake will be very high which would be uncomfortable for the inhabitants, and could lead to the fall of furniture and cause injuries. In the case of continuing earthquakes for a long time and the destruction of some of the boundary beams building resistant to earthquake will be reduced, patent application CN1144866 didn't present the design in the case of high-rise buildings and the extent of resistance to an earthquake in this case, and in patent application JP2004084385 structure is rectangular in shape and not subject to diversification of the shape.

e- Balance of the building and its resistance to earthquakes assumes that seismic wave is uniform, while the actual seismic wave is not uniform in direction and force, and what is the fate of the building in case of exposure to seismic shock from one point in Side one, in particular for patent JP2003328586 in additional to the interior space is limited and divided by shear walls,

f- Net area available for habitation is very small relative to total building area, and building will swing which make inhabitants feels uncomfortable. In addition to that Patent application US5502932 construction is very complex and requires special equipment to for execution, as well as friction coefficient between independent structures and elastic recovery device will make them as one body, which reduces the effectiveness of vibration damping. And in Patent application JP2011069148 over time cracks will occur between steel beams in the part set through reinforced concrete columns and concrete which exposes to corrosion due to moisture and weather factors as this part in not accessible for maintenance.

Problems and shortcomings in the other modern techniques used in the construction of high-rise building, which have been reviewed respectively are as follows: 1- The assumption that the direction of the wind steady throughout the year, while the direction of winds variable, therefore, needs to add a system to determine wind direction and accordingly changing the direction of fan rotation to change wind discharging direction, also a solution in the case of earthquakes has not been provided.

2- The method used to create the building is complex, particularly in the case of high-rise buildings and especially it is only to improve the performance of existing damping devices and not an integrated method, also it is too dangerous to hold building swinging to this method in case of destructive earthquakes.

3- Buildings made up from precast walls are limited in height and area, in case of building bent from any side due to wind or earthquake; the pressed concrete wall side will crash and a permanent deformation occurs.

4- Load the building on the ground depends on the type of soil and the extent of loads that it can bear by which it will limit the height and area of building that it can be constructed.

5- The structure of the building used very complex and requires a long time and high cost of implementation.

6. The actual-utilized area is very small relative to the total area of the building. General problems that the subject invention provides a solution to it which have shortcomings in the techniques that have been reviewed:

- The impossibility of constructing a super high-rise building symmetric in the area and size from the bottom to the top because of the bad effects of the wind on the structure.

- Reduction of high-rise buildings swinging with the wind, makes it more stable to improve both safety and susceptibility of living, and make it so people do not feel the dizzy.

- Resistance of the building to the effects that occur in high-rise buildings during earthquakes, which appear from the effects of shear deformation caused between the layers of the building and axial deformation of the column that it is cumulative to shear deformation. - Reduce the heavy weight of such buildings and reduce loads on the foundations making it suitable for construction in different soil types without the need for special equipment exaggerated needed for replacement of soil and the huge amount of piles to support the foundations of the building and even the sinking of the building into the soil does not happen over time.

- Make the rise building less complex in design, construction, and thus less time period required for execution, which up to ten years in some of them and thus be less costly.

- Increasing the areas effectively utilized in the building and not to waste precious space on a huge core wall or multiple shear walls which lead to limited interior space and divided into small intermittent and inappropriate areas.

- Securing the building from terrorist attacks and make them able to withstand such attacks with minimum possible losses.

- Solution to problem

Construction of a group of arms around building corners, each arm of them on a feather shape, these arms tied from the middle to building corners in multiple tying points along building height with tying the edges of each arm from multiple tying points along arm height with the two adjacent arms, all these connections are flexible using steel wire cables to work on the distribution of large part of building loads in the lateral outward direction to the group of arms and the remaining loads will be supported by building foundation. The building with the surrounding arms takes the form of a flower.

The number and size of arms vary depending on building form and height, also depending on loads and forces need to be outwardly distributed. The number of tying points between the building and arms are determined according to the distribution of center of gravities for each case. The building takes many shapes such as a circular cross-section or any regular polygon cross-section (triangle, square, pentagon, hexagon, octagon... etc.) or irregular cross-section.

These arms are tilted and outwardly curved so the closest point with the building base (contactless) and the farthest point with the building top, so that the curvature outwardly increase tying strength, fixation, and balance of the building. These arms are constructed from different steel sections or flexible concrete, and these arms are with small cross-section at the bottom and cross- section increases with height, also many holes should be set in these arms to prevent from being wind estop and to give the desired aesthetic view, provide ventilation, visibility, and day lighting necessary for building.

The benefit from using the subject method than using traditional methods that have been reviewed are as follows:

- The lateral distribution of a large part of building loads to the various arms surrounding the building; it is greatly reduced the loads on the foundations of the building, thereby enables building construction with minimum foundations, core wall and shear walls, as well as reduce the need for replacement of the huge amount of soil and quantity and size of piles required for supporting the building foundation in case of soft soil. All these factors contribute significantly to increasing building interior space resulting from reduced internal strengthening of building structure and increasing building heights other than traditional methods in different soil types without fear of collapsing risk, this confidence in the safety of the subject method resulting from reducing loads on foundations and achieve high balance to the building by these arms, also all that contribute to reduce cost of which was previously required in huge and expensive structure and foundation, and less time required for execution other than traditional complex and costly methods due to the simplicity and ease of constructing these arms, as well as minimum structure and foundations required.

- The building in this case is not only supported by foundations beneath, but also laterally using arms, which contributes significantly to increasing the effectiveness of building resistance to explosions. Where in the traditional methods the basis of building fulcrum and loading from its foundation, and when a bomb attack hits basement columns resulting in collapse of floors from the bottom to the top floor after floor, due to the collapse of the floor beneath, which is the basis support to it from top to bottom and the building will then totally _

collapsed, whereas when using the lateral outward load distribution arms prevent from above-mentioned bombing progression, and thus prevent from building collapse so that limiting damages in the lower floors directly exposed to the explosion, while upper floors will survive from destruction because of lateral outward load distribution not downward using arms.

- Traditional construction methods of high-rise buildings depends on very rigid structures and different damping techniques for resisting wind. Which increases construction cost, nevertheless building swing permanently occurs and felt by existing persons in upper floors of the building, which makes them feel dizzy and affect their psychological state with the continuation of this swing, when the building is exposed to strong winds occur from hurricanes this swing increases strongly leading to the fall of the internal contents of the building consequently casualties and injuries occur, when the wind exceeds a certain possible limit the building will collapse due to its dependence on the rigidity of building structure, robustness of the foundations, the effectiveness and the ability of damping systems used against such strong winds. While in the case of using multiple arms for lateral distribution of loads, then a multitude of lateral loading directions and numerous flexible tying points will be then using steel wire cables. Which works on the balance and stability of the building against winds with its different directions throughout the year, providing comfort and safety for inhabitants of upper floors. In the case of strong winds multiple lateral distribution points of the loads distributes wind load on building floors showing building flexible response with the wind and not against it, which appears in both building and arms swinging with such strong winds until it ends, keeping building safe from collapse due to maintaining balance of the building. Which is done with steel wire cables that distribute these loads in multiple lateral directions and do not be concentrated on one side, resulting from the focused single direction of such strong wind at this time.

- Seismic waves are not uniform in direction, which varies according to the depth and the direction of the earthquake source, its magnitude, and type of soil passing through it. Therefore, the seismic energy distribution varies along path of seismic wave, thus hit buildings at the same time with different direction and magnitude. So possible that hit a building with a certain direction and magnitude that make it collapse, and hit a nearby building with a different direction and magnitude that make it suffers damage can be dealt with. So the traditional methods based on support of the building in specific directions using core wall or shear walls, or rigid structure thwart the earthquakes, or vibration damping devices with time-bound in response and limited effectiveness. All of these methods when exposed to earthquake with a direction, magnitude and time period different than what it is designed, then the building will collapse with increasingly risk for greater height buildings. While in the case of using multiple arms for lateral distribution of loads, when earthquake hit the building from a certain direction with a certain magnitude, the steel wire cables tied between the building and the arm, that faces the earthquake hit will absorb the energy of this hit, and will make the building react in the opposite direction of this hit. Which assisted by steel wire cables that tying this arm with the two adjacent arms, which works on the distribution of earthquake effect on all building floors and not on a single point like other traditional methods which may cause building collapse, thereby reducing damages and save building, lives and property from harm, that is because these arms does not thwart or resist earthquakes as traditional methods, but give in to earthquakes flexibly until the end of the seismic wave, with easy maintenance and change of damaged (if any) steel wire cables after the situation stabilizes.

Modes for Carrying Out the Invention

1- One of the presented models for buildings supported with multiple peripheral arms for lateral distribution of loads of a regular hexagonal section building surrounded with six peripheral arms as shown in fig. 1 where the construction of the building (fig. 1 - sign no. 1) and the peripheral arms (fig. 1 - sign no. 2) to be executed in parallel time, and constructing both building and arms successively floors above floor, and after completion of each phase of building construction then to be tied with the six peripheral arms using steel wire cables (fig. 1 - sign no. 4) from tying points in building corners (fig. 1 - sign no. 8) and tying points in the middle of each arm (fig. 1 - sign no. 7), then the six arms to be tied to each other, so that each arm to be tied to the two adjacent arms from edges (fig. 1 - sign no. 6) using steel wire cables (fig. 1 - sign no. 3), and many holes (fig. 1 - sign no. 5) should be set in these arms to prevent from being wind estop. 2- After completion of construction for both building and peripheral arms the form becomes as shown in fig. 2 of sectional view which illustrate the details of section A - A in fig. 1 , where the building (fig. 2 - sign no. 1) completely tied all over its height from multiple tying points (fig. 2 - sign no. 8) in the building with other multiple tying points (fig. 2 - sign no. 6) in the peripheral arms (fig. 2 - sign no. 2) on the same horizontal plane using steel wire cables (fig. 2 - sign no. 3). These arms are tilted and outwardly curved so the closest point with the building base (contactless) and the farthest point with the building top, so that this curvature outwardly create a lateral outward tension force which maintains building balance from all directions. This method is used for both concrete and steel buildings while peripheral arms to be constructed from different steel section types or flexible concrete.

3- Peripheral arms would be in the form of a feather as shown in fig. 3, where the smallest cross-section at the bottom and cross-section increases with height, so that the biggest cross section area at the top of these arms (fig. 3 - sign no. 2), also many holes (fig. 3 - sign no. 5) should be set in these arms with a proper density to discharge wind to prevent from being wind estop to not produce unwanted additional forces on these arms, building in tied to these arms using steel wire cables (fig. 3 - sign no. 4) from multiple tying points (fig. 3 - sign no. 7) in the middle of these arms along its height, also each arm to be tied to the two adjacent arms from the edges using steel wire cables (fig. 3 - sign no. 3) from multiple tying points (fig. 3 - sign no. 6) in the edges of this arm along its height.

4- Another model from the presented models for buildings supported with multiple peripheral arms for lateral distribution of loads of a regular rectangular section building surrounded with four peripheral arms as shown in fig. 4 where the construction of the building (fig. 4 - sign no. 1) and the peripheral arms (fig. 4 - sign no. 2) to be executed in parallel time, and constructing both building and arms successively floors above floor, and after completion of each phase of building construction then to be tied to the four peripheral arms using steel wire cables (fig. 4 - sign no. 4) from the tying points in building corners (fig. 4 - sign no. 8) and the tying points in the middle of each arm (fig. 4 - sign no. 7), then the four arms to be tied to each other so that each arm to be tied to the two adjacent arms from edges (fig. 4 - sign no. 6) using steel wire cables (fig. 4 - sign no. 3), and many holes (fig. 4 - sign no. 5) should be set in these arms to prevent from being wind estop.

5- Also another model from the presented models for buildings supported with multiple peripheral arms for lateral distribution of loads of a regular octagonal section building surrounded with eight peripheral arms as shown in fig. 5 where the construction of the building (fig. 5 - sign no. 1) and the peripheral arms (fig. 5 - sign no. 2) To be executed in parallel time, and constructing both building and arms successively floors above floor, and after completion of each phase of building construction then to be tied to the eight peripheral arms using steel wire cables (fig. 5 - sign no. 4) from the tying points in building corners (fig. 5 - sign no. 8) and the tying points in the middle of each arm (fig. 5 - sign no. 7), then the eight arms to be tied to each other so that each arm to be tied to the two adjacent arms from edges (fig. 5 - sign no. 6) using steel wire cables (fig. 5 - sign no. 3), and many holes (fig. 5 - sign no. 5) should be set in these arms to prevent from being wind estop.

6- Three dimensional graphical representation of the model of a regular hexagonal section super high-rise building surrounded and supported with six peripheral arms is presented in figs. 6 - 10 for more clearly representing the idea of lateral distribution of loads using peripheral arms and steel wire cables.

Industrial Applicability The presented Building after construction completion surround from corners and tied to peripheral arms using steel wire cables. This system works on the distribution of major part of different building loads from weight, wind and earthquakes when exposure to them laterally to the peripheral arms, so that reduces the loads on building structure and foundations, which enables to be less in size and consequently increases utilized areas, also enables the construction of super high-rise buildings in soft soil while reducing the required volume of soil replacement and size of piles after the lateral distribution of loads to the peripheral arms, and thus less cost and time needed for construction.

The outward curvature of the arms increases the tension forces in the steel wire cables which maintains laterally outward distribution of building loads and building balance against various loads, and secure top floors of the building, which helps to increase their height.

The holes being made in these arms with an appropriate geometric pattern give the desired aesthetic view to the present building method at the same time discharges wind to not produce and additional forces on these arms when exposed to winds in order to increase the effectiveness of these arms, and also provide ventilation, visibility, and day lighting necessary for building.

The building when exposed to bombing attack, the damages will be limited on lower floors which are directly exposed to the explosion, while the upper floors will survive from destruction because loading is directed laterally outward in the arms and not too down direction. The multiple arms for lateral distribution of loads will vary the direction of lateral loading and the provided flexible tying points using steel wire cables. Which works on the balance and stability of the building in front of the wind with its varying directions throughout the year. Also provides for the residents of the upper floors comfort and safety, and in the case of strong winds multiple lateral distribution points of the loads distributes wind load on all building floors showing building flexible response with the wind and not against it. Which appears in both building and arms swinging with such strong winds until it ends keeping building safe from collapse due to maintaining the balance of the building, which is done by steel wire cables that distribute these loads in multiple lateral directions and do not be concentrated on one side resulting from the focused single direction of such strong wind at this time.

When an earthquake hit the building from a certain direction with a certain magnitude. The steel wire cables tied between the building and the arm that faces the earthquake hit will absorb the energy of this hit. And will make the building react in the opposite direction of this hit, and assisted by steel wire cables that tying this arm with the two adjacent arms, which works on the distribution of earthquake effect on all building floors, thereby reducing damages and save building, lives and property from harm, that is because these arms will give in to the earthquake flexibly until the end of the seismic wave, with easy maintenance and change of damaged (if any) steel wire cables after the situation stabilizes.
