中国、欧洲钢-混凝土组合梁的设计规范比较

根据欧洲规范4和中国《钢结构设计规范》对简支组合梁的设计过程进行了对比，包括施工阶段与组合阶段承载力验算、剪力连接件设计、剪力验算、挠度验算及自振频率验算等。给出了相关工程实例计算并对设计结果进行了比较。结果表明：欧洲规范4对于钢-混凝土组合梁的设计过程的规定更加详细，通过中国《钢结构设计规范》进行设计所得的结果较欧洲规范4保守。

Design Code Comparison of Steel-Concrete Composite Beam of China and Europe

According to European standard Eurocode 4(EC4) and Chinese standard code for design of steel structures,the simple composite beam was contrasted in the design process.The items to be designed included moment resistant in construction and composite stage,bearing capacity checking computation,shear connectors design,deflection checking computation,natural vibration frequency checking computation and so on.The related engineering examples in calculations were given and the results of design were compared.The results show that the correlative provision in EC4 is more detailed than that in Chinese standard code for design of steel structures which is more conservative.
