【摘要】 简要介绍了中美规范抗震设计的基本设计原则和方法,并比较了两者的主要差别和异同,进而根据中美混凝土结构设计规范关于抗震承载力验算的有关设计规定,以我国规范丙类建筑四级抗震等级的混凝土基本构件为基准,从分项系数设计表达式的相当安全系数的角度,对中美规范混凝土结构基本构件抗震承载力的安全度设置水平进行了计算分析和比较,获得了中美规范混凝土结构基本构件抗震承载力安全度设置水平差异的定量数据,并对我国规范抗震承载力验算的有关设计规定提出了若干修订建议,可供工程应用及今后我国规范修订时参考.更多还原

【Abstract】 The basic principles of aseismic design in Chinese and Amercian codes are introduced;and the differences between the codes are compared.Based on the codes about the concrete structural components aseismic bearing capacity checking,between Chinese and Amercian concrete structure design codes,taking the basic concrete components of Chinese structure seismic level of four,seismic design category for standard fortification class as the benchmark,from the perspective of safety factor of the subfactor design expression,calculating and comparing the safety level set of the aseismic bearing capacity of the basic components checked for the concrete structure in the Chinese and American codes,the quantitative data of the difference in the safety level of the concrete structural components aseismic bearing capacity between Chinese and American codes are obtained.A number of amendments on the checking of aseismic bearing capacity of Chinese code are suggested;that can be for reference in engineering applications and future revisions of Chinese codes.更多还原
