从我国抗震设计的基本原理出发，阐述了钢筋砼框架柱的延性设计，认为应进一步增大作用效应，以提高结构设计的可靠度，保证结构良好的承载能力与变形能力．同时分析了塑性铰区抗剪强度退化机理，提出了有关抗剪承载力计算、约束箍筋等的修正建议，以供规范修订时参考 Based on the basic principles of seismic design in our country, the ductile design of reinforced concrete frame columns is described. It is believed that the effect should be further increased to improve the reliability of the structural design and ensure a good bearing capacity and deformation ability of the structure. At the same time, the mechanism of shear strength degradation in plastic hinge areas was analyzed, and the correction suggestions on the calculation of shear bearing capacity, constrained stirrups, etc. were proposed for reference in the specification revision.
