摘要
针对汶川地震中楼梯的严重破坏,探讨了有限元分析软件ANSYS对混凝土板式楼梯的动力时程分析,通过瞬态分析对梯段板施加冲击荷载,对比分析了在同样大小的静载和冲击荷载作用下,梯段板挠度和应力的变化。
In light of the stairs heavy damage in Wenchuan earthquake,this paper discusses the finite element analysis software ANSYS to carry on the dynamic time-travel analysis to the concretes slab stairs,and through the transient analysis of the stair slabs to impose impact load,compared and analyzed in the same size of static load and impact load,stair slabs amount of deflection and stress change.
