中国、印度、孟加拉规范设计地震反应谱比较

Comparison of Design Seismic Response Spectrum of Chinese,India and Bangladesh Codes

介绍和分析了中国、印度、孟加拉现行规范的设计地震反应谱计算方法,对设计反应谱的重现期、地面运动加速度峰值、场地土分类原则、结构响应折减系数、重要性系数等影响设计反应谱取值的参数进行了讨论,并就几种典型情况下的三种反应谱取值进行了比较,分析了对比较结果影响较大的因素。

This article introduced and analyzed the design seismic response spectrum of present China,India,Bangladesh codes,discussed the parameters that affect design response spectrum,i. e. return period of design response spectrum,peak ground acceleration,site classification principle,structure response reduction factor,importance factor etc. It also compared these three response spectrums under certain circumstances,and analysed the factors that greatly affect comparison result.
