【摘要】 从上部混凝土结构初步设计相关的主要参数设定上,比较中欧规范的异同。中欧规范对结构重要性的分类、设计使用年限的分类基本一致,各类极限状态下的组合表达式形式基本一致,但在荷载分项系数上有差异。同中国规范相比,欧洲规范的活荷载整体取值更高,对雪荷载的计算更为细致,对风荷载的计算有一定区别。中欧规范对普通钢筋的强度和延性的要求类似,混凝土强度设计值差别不大,但欧洲规范对耐久性要求更高。在参考欧洲规范设计时,应注意基本组合的选择和国家附录对部分参数取值的变化。更多还原

【Abstract】 Parameters in Chinese and European codes for multistory concrete structures were compared.Specifications related to consequence definition,design life,and load combination in Chinese code are similar to those in European code.However,the values of loading factors are different between two codes.Comparing to Chinese code,the values of the uniformly distributed live loads are larger in the European code.The calculating methods about snow loads are simialr but the specification about wind loads are different in two codes.In both codes,steel strength is similar but concrete strength is slightly different.Durability is more demanding in European codes.Therefore,parameter seletion and load combination need to be carefully considered when using the two diffferent codes.更多还原
