EARTHQUAKE RESISTANCE REINFORCEMENT STRUCTURE OF PASSENGER SHED

Japanese Patent JP2023016605

A

To provide an earthquake resistance reinforcement structure of a passenger shed allowing the reinforcement of earthquake resistance in a column weak axis direction effectively and easily when the weak axis direction of the column of the passenger shed is in parallel with a railway track.SOLUTION: A passenger shed to which the invention is applied comprises a plurality of columns 2 made in H-shaped steel and erected on a foundation, a plurality of beams 3 connected to the plurality of columns 2 and a roof 4 placed on the plurality of beams 3 and it is adjacent to a railway track RW. The column 2 has its weak axis direction in parallel with the railway track RW. An earthquake resistance reinforcement structure of the invention comprises a viscous damper 6 provided between the column 2 and a railway track parallel beam 3 P and restricting vibration by a viscous damping effect in a plane of structure configured with the column 2 and the railway track parallel beam 3 P extending in the weak axis direction and a cover plate 5 mounted to a leg part of the column 2 so that its main plane is orthogonal to the weak axis direction.SELECTED DRAWING: Figure 2
