| Abstract: | In view of the characteristics of the rural residential areas,a new type of seismic practical technology called steel-asphalt composite isolation pier with economic,simple and reliable characteristics is put forward.Specimens are made according to the correlation theory.By comparing the input El Centro and Taft ground motions and structural seismic responses in shaking table tests,dynamic characteristics of this isolation pier are studied.The test results show that:the acceleration reduction factor of isolation pier is between 0.34～0.55 and the isolation pier absorbs the seismic energy very well.This is an economical technology and could be widely used in areas with different seismic fortification intensity even for the rare earthquake with the peak ground acceleration reaching 1.5g. |
