| Abstract: | According to the demand of bridge seismic design in high speed railway and the idea of bearing function separation,this report presents some appropriate results of the hysteretic behavior and energy dissipation capacity of absorber under the low cycle loading experiment.And it shows that the ductility and energy dissipation capacity of absorber performace well at low cycle loading,and the stiffness in linear elastic phase is improved,which meets the requirement of the railway bridge design. |
