地震作用下楼梯破坏机制研究

Research on stairs failure mechanism under earthquake action

根据汶川地震和玉树地震中楼梯的破坏情况,系统分析了现存建筑物结构中楼梯在地震作用下的破坏形态及破坏原因,并提出了相应的设计建议,对今后的楼梯抗震设计具有一定参考价值。

According to the stairs failure situation of Wenchuan earthquake and Yushu earthquake, this paper system analysis on the failure pat- terns and reasons of stairs under earthquake of existing buildings structures, and put forward corresponding design suggestions, had a certain ref- erence value for future stairs seismic design.
