【摘要】 抗震设计反应谱是结构抗震设计的主要依据,设计反应谱的标定是确定地震动输入的重要环节。文中详细地总结了设计反应谱标定的基本原理和几种常用的设计反应谱标定方法,介绍了我国建筑抗震设计反应谱参数的确定方法和"统一抗震设计反应谱"的研究现状及应用前景;对不同设计反应谱标定方法中存在的问题进行了评述;提出抗震设计反应谱标定方法中有待进一步研究的问题。更多还原

【Abstract】 Seismic design response spectrum is the basis of structural seismic design.Calibration of the seismic design response spectrum is the main chain of determining structures’ seismic input.The basic theory and several methods of determining design response spectrum are summarized,the calibrating methods of the seismic design response spectrum in our country are introduced,the present studied state of "Uniform Seismic Design Spectrum" and its application foreground are discussed,then the problems of every method are pointed out and the problems which worth more research in future are provided.更多还原
