Displacement Based Seismic Design Method of RC Frame with Friction Dampers

Abstract:

Displacement based seismic design of RC frame with friction damper is proposed in this paper based on the displacement shape of RC frame. and multi-degree-of-freedom system is transformed into an effective single-degree-of-freedom system. Based on equivalent linearization equivalent period is determined by using the elasto-plastic displacement response spectra, and then the structural members are designed. At the same time, target deformability of the frame and friction damper device is obtained by decomposing the structural storey drift. And the expected deformability of the structure can be guaranteed by appropriate the friction energy dissipation brace. This method could effectively control the seismic performance of the structure in earthquakes.
