错层板柱与普通板柱结构体系的弹塑性分析

Elastic Plastic Analysis of Staggered Floor Slab Column and Normal Slab Column Structure System

错层板柱结构用地率高、层高低、造价节约,在停车库建筑中应用广泛[1]。但错层使楼板错置,削弱了楼板协调结构整体受力的性能。同时形成竖向短构件,受力集中。本文通过时程分析法对对两种结构进行水平地震作用下弹塑性分析,找出错层板柱结构的的抗震薄弱点。

Staggered floor slab column structure has high land use rate, low layer and low cost, so it is widely used in parking building. But the staggered floor will weaken the performance of internal force coordination. At the same time it forms the short component and causes the stress concentration. In this paper, the elastic plastic analysis of two kinds of structure is conducted through the time history analysis under horizontal earthquake action to find out the weak points of the staggered floor slab column structure.
