Equivalent Sdof System Model for Estimating the Seismic Response of Building Structures With Displacement-Dependent Passive Dampers


Abstract eng:
In this paper, an equivalent SDOF system model of a multi-story frame with displacement-dependent dampers is proposed to estimate the seismic response. The proposed equivalent SDOF system model has multi-spring to take into account the hysteretic behaviors of frame and damper elements. The properties of multi-spring converted from dampers are defined by an elastic mode vector obtained from the eigenvalue analysis of the frame with dampers and properties of dampers. To confirm the validity of the proposed model, seismic responses of elaborate analytical models of three-story steel moment resisting frames with displacement-dependent passive dampers and their corresponding equivalent SDOF system models were compared. The drift demands in the SDOF system are mapped back to building structures with damper based on the performance-based design method in Japan. According to the results, the proposed equivalent SDOF system model has sufficient accuracy for evaluation of the seismic responses.
