In all the codes, site-specific response spectra are recommended. Finally inelastic design spectra are also discussed.S. RajasekaranStructural Dynamics of Earthquake Engineering
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...

The strength reduction factor spectra of constant ductility factor for bidirectional ground motions is developed by considering the multi-component earthquake excitation and coupled characteristics of structural response, which is defined as the ratio of the maximum displacement response in the same ...
The equipment can conduct a full chain of earthquake scenario simulation: based on source physical processes, seismic wave propagation paths, site conditions, and building structures. Seismic scenarios of different sources, site conditions, floors, and response spectra are used to study human perception...
We have developed empirical equations for predicting earthquake response spectra in terms of magnitude, distance, and site conditions, using a two-stage regression method similar to the one we used previously for peak horizontal acceleration and velocity. We analyzed horizontal pseudo-velocity response ...
