[摘要]楼板作为主要水平构件,不仅需要承受和传递荷载,而且需要协调各抗侧力构件之间的变形。高层建筑结构楼板设计时,目前只考虑竖向荷载引起的面外弯矩,而忽视了水平荷载作用下产生的楼板面外弯矩和面内内力的影响,对高层建筑楼板面内应力分析与设计进行了探讨,介绍了常用计算程序中分析应力的方法,给出了楼板承载力验算方法。通过工程案例说明了方法的应用。

Abstract:As the main horizontal member, slab not only needs to bear and transfer load, but also has to coordinate the deformation between the horizontal resisting members. Only out-of-plane moment caused by vertical load is considered in the current design of high-rise building slabs, while ignoring the influence of out-of-plane moment and in-plane internal force under horizontal load. The in-plane stress analysis and design of slabs of high-rise building were discussed, and the stress analysis methods of the slab in calculation program were introduced and the checking method of slab bearing capacity was provided. Finally an engineering example was given to explain the application of the method.
Keywords:out-of-plane moment; in-plane stress; horizontal load; calculation program; slab bearing capacity
