摘要
我国混凝土结构设计规范参考国外标准增加了并筋构造措施。本研究通过具体算例,对中美欧混凝土结构设计规范关于并筋锚固长度以及构造措施进行了分析。结果表明:受拉钢筋的锚固长度,美国规范的计算值大于中国国家标准和欧洲标准的计算值,随着并筋等效直径增大,计算结果差值增大;相较于美国规范,中国国家标准和欧洲规范的锚固长度曲线变化趋势及计算值接近。
Based on foreign codes,details of bundled bars have been revised in China concrete design specification. Anchorage length and details of bundled bars in concrete structure design code of Chinese,American and European were analyzed by some examples.The results show that calculated value of tensile reinforcement anchorage length according to American code is greater than Chinese and European codes,with the increase of the equivalent diameter of bundled bars,the differences between the results increased. Compared with the US specification,the Chinese standard and European standard of anchorage length curve trend and the calculated value is close.
