摘要
本文从变形能力与破坏机制的角度对框架-剪力墙结构中柱轴压比限值的合理性进行了讨论,指出轴压比限值应根据柱所处位置的不同而加以区别.本文对影响柱延性的主要因素以及改善变形能力的措施进行了阐述,提出两种旨在提高柱承载能力的配筋方式,引入等效轴压比的概念代替传统的轴压比.
The rationality of the limit value of axial compression ratio of columns in frame-shear wall structures is researched from the viewpoints of deformation capacity and yielding mecha-nism in this paper. It is pointed out that the limit values of axial compression ratio of columns should be applied according to their different locations in structures. The main factors affecting the ductility of columns are reviewed, and two methods are proposed for improving the bearing capacity and ductility of the traditional RC columns.
