中国、英国钢-混凝土组合梁设计规范比较

Design Code Comparison of Steel-Concrete Composite Beam between China and Britain

根据中国《钢结构设计规范》和英国规范(BS5950),对简支组合梁的设计过程进行了对比,包括施工阶段与使用阶段承载力的验算、抗剪连接件的设计和挠度验算等.通过相关工程实例计算,对设计结果进行了比较,结果表明:英国规范对于钢-混凝土组合梁设计的规定更加详细,由设计所得的结果较中国规范更加保守.

According to Chinese standard （Code for design of steel structures） and British standard （BS5950）, the design process of simply supported composite beam was compared. This content included moment capacity during construction stage and composite stage, shear connectors design, deflection checking, etc. A related engineering example was given and the design results of these two standards were compared. The results show that the correlative part in BS5950 is more detailed and leads to more conservative result than those in Chinese standard.
