框架结构中楼梯的抗震设计分析

On anti-seismic design analysis of stairs in frame structure

对某框架结构的四种不同楼梯形式进行了抗震分析,探讨了其在小震、中震及大震作用下楼梯及结构的周期、位移、受力等变化情况,为框架结构的楼梯设计提供了有益的参考。

The paper undertakes the anti-seismic analysis of four stair forms of some frame structure, explores the changes at the stairs, the peri- od, the displacement, and the stress of the structure under the small earthquake, the middle and large earthquake, so as to provide the helpful reference for the stair design for the frame structure.
