Abstract

Based on the idea of bearing function separation, a structural member called shock absorber that makes use of its plastic deformation, is presented for reducing the seismic response of the bridge. The design criterion, for matching material stress, strain and earthquake fortification aim, is also given. The analysis results show that the high speed railway box girder with the absorber in this paper has great reduction of seismic response of the bridge piers.
