摘要
配置约束箍筋对保证框架柱抗震性能具有重要作用。通过算例计算分析,综合对比了中国、美国、新西兰、欧洲的混凝土结构设计规范体积配箍率及相关构造措施规定,对中国规范相关内容提出了修改建议。
The confinement stirrups in the potential ductile plastic regions is an important guarantee of the seismic performance of frame columns. The requirements for confinement stirrups in potential ductile plastic regions of frame columns specified in the concrete structure standards / codes developed by China,the United States,New Zealand and Europe are compared comprehensively. Through the calculating examples,the influences of axial compression ratio,strength of stirrup and concrete on the limits of volume-stirrup ratio are analyzed,and some recommendations of modification as to the relevant contents of Chinese code were presented.
