Abstract

As a new damper which is suited to seismic retrofit for existing high-rise buildings, the authors have developed a passive variable friction damper (VFD) with displacement dependent damping force characteristics. In the present paper, in order to evaluate the response control effects of high-rise buildings incorporating VFDs, earthquake response analyses were conducted using thirty-story frame structure models with VFDs, with conventional friction dampers, or without dampers. The results indicated that VFDs can mitigate response story shear forces and column axial forces compared with conventional friction dampers.
