中美抗震规范有关地震作用计算规定的差异

摘要

Based on the study on provisions on seismic action specified in GB50011-2010 (China) and ASCE / SEI 7-10 (USA),this paper in detail com-pares the differences of response spectra between the two countries, including the basic regulations of response spectrum curves, the influence of site types and the relative difference of response spectra. Besides, the paper also compares the calculation methods of horizontal seismic action and the shear force of a frame structure by applying the static calculation method in GB50011-2010 and ASCE/SEI 7-10 respectively.%在对中国GB 50011-2010规范[1]和美国ASCE/SEI 7-10[2]规范中的水平地震作用进行对比研究的基础上,详细对比了中美规范中设计反应谱的差异,主要包括了反应谱曲线的基本规定、场地类别的影响和反应谱取值. 此外,还对比分析了中美规范中水平地震作用计算的差别,并以一个三层框架结构为例,分别根据GB 50011-2010和 ASCE/SEI 7-10,采用底部剪力法(等效侧向力法)进行了对比分析.
