Numerical analyses of seismic behavior have been completed on a steel frame structure with a T-shaped core plate frictional damper by applying ANSYS in Tianjin city in the present paper.

In this paper, based on the configuration and mechanical characteristics of piezoelectric actuator and T shape friction damper, a piezoelectric-T shape variable friction damper is presented and its damping model is established corresponding to actively adjusting input voltage or adjusting input voltage in displacement-dependent and velocity-dependent modes.
