板式楼梯的抗震性能设计

Performance-Based Seismic Design of Plate Stairs

通过板式楼梯的典型震害分析,揭示结构破坏机理。通过对多遇地震、设防烈度地震,预估的罕遇地震作用下的竖向地震作用组合抗震计算,总结板式楼梯抗震验算的基本规律,并给出了切实可行的抗震构造措施。

This paper reveals the seismic damage mechanism of the plate stairs through researching the typical earthquake damage investigations and analyses. The seismic behaviors of plate stair structures under the loads of intensity of frequently occurred earthquake, seldom occurred earthquake and earthquake fortification are studied separately, and afterword some useful rules are gained. Then some practicable details of seismic design are suggested.
