Friction dampers dissipate energy through the friction that develops between two solid bodies sliding relative to one another. When a major earthquake occurs, the friction damper slip at a predetermined load before yielding occurs in members of a frame, which dissipate a major part of the energy. It saves the initial cost of new construction or retrofitting of existing building, with a very high energy dissipation.
In this paper, the seismic performance of a code-designed 14 story moderately ductile concrete frames with and without friction dampers located in Victoria, BC, in the western part of Canada has been studied and the results of the initial costs have been compared. Pushover analysis has been used to investigate the different performance levels of the building, and nonlinear dynamic time history using a set of ground motion records has been performed to determine their effects. Moreover, the Equivalent Lateral Force Procedure for structures with damping systems according to FEMA 450 has been calculated and compared with the results obtained according to NBCC 2015.
Keywords: seismic performance, performance-based design, concrete structures, friction dampers, moderately ductile.
