根据中美混凝土结构设计规范关于承载能力极限状态的有关规定,本文从综合安全系数的角度,对中美混凝土结构设计规范中常用的拉、压、弯、剪、扭及板受冲切等8种典型的基本构件的综合安全系数进行了计算分析和比较,获得了中美混凝土结构设计规范安全度水平差异的定量数据,据此提出了调整我国现行规范安全度设置水平的有关建议,可供规范修订时参考。
According to the relevant provisions of China-US Concrete Structure Design Code on ultimate capacity of bearing capacity, this paper analyzes the commonly used drawing, pressing, bending, shearing, twisting and plate punching of concrete structures in China and the United States from the perspective of comprehensive safety factor. The comprehensive safety factor of typical basic components has been calculated and analyzed and compared to obtain the quantitative data of safety level difference between China and the United States concrete structure design codes and put forward some suggestions on how to adjust the current national standard safety level setting Reference when revising the specification.
