Title:
PRE-STRESSED STEEL BEAM WITH A VARIABLE CROSS-SECTIONAL AREA
Document Type and Number:
WIPO Patent Application WO/2021/053696
Kind Code:
A2
Abstract:
The determining factor in designing beams is usually the flexural moment. In designing structures, engineers are restricted in planning structures with a wide span in that in these structures, the flexural moment becomes so huge that makes the construction of such structures practically impossible. Moreover, the nature of flexural moment does not allow one to make use of the total capacity of the used steel along the span. In such structures, at the spot where the maximum flexural moment is experienced, the beam gets to the fracture point, while at the other points along the beam, it does not even get to yield point. Therefore, a huge part of the capacity of the implemented steel remains useless in practice. The primary purpose of the present invention is to improve the efficiency of the capacity of the steel used in flexure elements, and to increase the span size to feasible dimensions.
