A new type of friction damper is proposed,which has simple structure and clear working mechanism.It can provide the friction force changing with the change of displacement.A continuous hysteretic model is given to describe its mechanical properties.The nonlinear comparison and analysis between the new type of friction damper and the common friction damper are carried out.The results show that:In the case of different seismic waves,the new friction damper proposed in this paper has the best control effect on the displacement and acceleration of the system.
