带转换层的混凝土异形柱结构设计及分析

针对带转换层的混凝土异形柱结构，进行了多遇地震下的弹性动力时程分析和罕遇地震作用下的弹塑性分析，结果表明：内折角处异形柱出现应力集中，构造和配筋上应给以加强；在设计中应根据转换层上下竖向构件的重要性，适当放大抗震等级，同时严格控制轴压比。

Design and Analysis of Structures with Concrete Special-Shaped Columns and Transfer Stories

Elastic time-history response analysis under frequently occurred earthquakes and elastic-plastic analysis under rare earthquakes were executed,of structures with concrete special-shaped columns and transfer stories.It shows that stress concentration occurs on the special-shaped columns in the inner corner,so the composition and reinforcements should be strengthened there,and that in the design aseismic grade should be properly enlarged,as well as the axial compression ratio is strictly controlled,according to the importance of the vertical members near the transfer stories.
