Abstract
Dual-Pipe Damper (DPD) is a metallic yielding device for the passive earthquake energy dissipation. It consists of two welded pipes, which is positioned to take shear. DPD works in flexural form, on the basis of plastic-deformation of steel materials. According to previous researchers, multistory frames equipped with DPD exhibit a stable hysteresis loop with excellent energy absorption capacity under dynamic non-linear time—history analysis. Present study investigates the lateral resisting capacity of DPD by pushover analysis and to find out the best dimensions of DPD for buildings conforming to IS 800:2007. From this study, the optimum frame equipped with DPD is identified which can be utilized for a better seismic retrofitting.
