| 摘 要： | 2008年汶川大地震中,不l同结构类型建筑的楼梯发生了不同程度的破坏,其中框架结构的楼梯破坏最严重.文中分析了砌体结构、框架结构、框剪结构的楼梯破坏原因.表明楼梯实际上参与了主体结构抗震,在整体结构中起着斜撑的作用,为限制结构层间位移作出了贡献,与目前的结构分析软件不考虑楼梯参与主体抗震作用,仅将其作为荷载加到主体结构...

| Abstract: | some stairways or staircases were destroyed in Wenchuan earthquakes.The damage was commonly caused in stairway beam,stairway slab,the connection of stairway flight and rest platform,and the stairs beam-column joint of masonry or frame or frame-shear wall building.In design,the contribution of stairway to earthquake-resistance was neglected,but in fact,the staircase acts as inclined brace in whole structure,which will resist the lateral deflection of main structure.In order to reduce the negative influence o... |
