摘　　要：分别介绍GB 50011-2010《建筑抗震设计规范》和GB 18306-2015《中国地震动参数区划图》反应谱的异同,包括加速度记录数据样本及分组、数据处理、反应谱的构建和应用,进而讨论了地面峰值加速度(GPA)和有效峰值加速度(EPA)的定义。分析了8组地震动加速度记录的反应谱,结果表明,采用GB 50011-2010《建筑抗震设计规范》进行结构时程分析时,输入地震动加速度值应按EPA调整,计算结果与振型分解反应谱法对比才有意义。A comparison of acceleration response spectra between GB 50011-2010‘Code for seismic design of buildings’and GB 18306-2015‘Seismic ground motion parameters zonation map of China’was conducted on acceleration data bases,data process,formation and application of design response spectra,and then the definition of ground peak acceleration(GPA)and effective peak acceleration(EPA)are discussed in this paper.Based on eight samples of acceleration record,it is shown that the time history analysis of structures is meaningful and valuable when the peak acceleration is adjusted by EPA.
