Background
Aiming at the damage condition of the earthquake to the house, the staircase is found to be seriously damaged by a plurality of post-earthquake investigations of major earthquakes. The reason is that the rigidity of the staircase is increased due to the inclined strut function of the stair section plate and the short column function of the half-layer connection of the rest platform plate and the staircase frame column, and excessive energy absorbed by the staircase is firstly damaged when an earthquake occurs. The regulations and stairs in the 'building earthquake-resistant design Specification' revised after Wenchuan earthquake should participate in the overall calculation, and the purpose is to consider the real influence of the stairwell on the main structure. However, in engineering practice, when the stairs enter the overall structure model for calculation, the calculation result is often abnormal, and the calculation result is difficult to be used in a design file. And because the seismic force is excessively distributed to the inclined strut formed by the staircase stair section plate and the frame column connected with the inclined strut in calculation, the seismic force distributed by other frame columns is smaller, if the theoretical calculation result is used in the actual design, once an earthquake higher than the fortification intensity occurs, not only the staircase frame column can be damaged, but also other frame columns can be continuously damaged due to insufficient safety reserve.
Therefore, the national standard drawing set 16G101-2, which is a concrete structure construction drawing plane overall representation method drawing rule and a construction detail drawing (cast-in-place concrete slab stairway), recommends a method of arranging a sliding support at the beginning of a stair section plate to eliminate the diagonal bracing effect of the stair section plate. But the stair rest boards are still supported on the frame posts of the stairwell, so this approach does not remove the constraint between the rest boards and the stairwell frame posts. The problems of local split floors, short columns of frame columns, complex stress, easy first damage during earthquake and the like caused by the stair platform beams and the platform plates arranged on the half floors are not completely solved. This problem is particularly acute for somewhat more complex staircases, such as a broken line staircase, a girder staircase, when no sliding abutment is provided.
