Design of friction dampers for seismic response control of multistory frames requires three questions to be addressed (a) optimum parameter values of individual friction damper (b) location and maximum number of friction dampers along the building height and (c) sequence of allocation of dampers. The present work addresses these three problems using newly introduced slip factor sf and story dissipation potential index (SDPI). The solution provided takes into account the optimum performance of the damper while ensuring response reduction in the frame. The proposed method is compared with the well known simplified sequential search algorithm (SSSA) for damper allocation. Finally, response of a 2D frame with inelastic frame members is presented to show the effectiveness of the proposed method in design of frames.
