常用的地震反应谱(Commonly used Response Spectra) (1)反应谱(Response Spectra) 当最大响应分别取相对位移、相对速度、绝对加速度时,我们可获得以下反应谱: 相对位移反应谱: 相对速度反应谱: 绝对加速度反应谱: (2)伪反应谱(Pseudo-Response Spectra) 另外,工程中还常用到伪反应谱。所谓伪反应谱是指,当我们获得...
Seismic Response Spectra is an important concept in earthquake engineering, we often need to evaluate seismic response spectrum on the basis of a given time-acceleration record.SPECTRconstitutes an easy way to evaluate Seismic Response Spectra, featuring a user-friendly visual interface. It is a help...
