We obtain the absolute acceleration response spectrum,then a new attenuation relationship,which is between the small and moderate earthquakes on bedrock site in Fujian region,is given.

Research on earthquake acceleration response spectrum of frozen soil ground;

Due to insufficient consideration of influence of input seismic load response spectrum on aseismic calculation of earth-rock dams,the influences of acceleration response spectrum,velocity response spectrum,and displacement response spectrum of input earthquakes on seismic response of earth-rock dams were analyzed.

The paper has studied and discussed the amplification of incident waves about acceleration time-domain and acceleration response spectrum in local deposit on the bedrock of single layered soil .

From the statistical average elastic acceleration response spectra,an elastic acceleration response spectra formula of near-fault ground motions is proposed;and based on it the inelastic acceleration response spectra formula is suggested too.

Based on the strong ground motion data, we adopt empirical attenuation relationships and utilize regression statistical analysis method to study the relations between vertical and horizontal acceleration response spectra.

This method was applied to plenty of floor system analyses with different performance objectives,shapes and boundary conditions,and a formula of acceleration response spectra was obtained by regression method based on the multiple-degree of freedom model for the floor vibration.

For studing of the dynamic response of buildings on the impact of earthquake waves,the pseudo-acceleration response spectrum will usually be introduced.

Active control with absolute acceleration feedback;

It is showed by analytical result that the basic reason of these problems is caused by absolute acceleration′s mutation of mechanism.

Dynamic characteristics of ATMD control are discussed in two complete-feedback modes based on absolute acceleration of the structure and ATMD (Because,in fact,the acceleration sensor detects the absolute acceleration).
