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。
Confining restraining stirrups plays an important role in ensuring the seismic performance of frame columns. Through the calculation and analysis of the examples, the author compares the volumetric hoop ratio of concrete structure design codes in China, the United States, New Zealand and Europe and the relevant construction measures, and puts forward some suggestions for the revision of the relevant contents of Chinese norms.
