Improving Seismic Performance of Concrete Buildings with Special Moment Frames Using Viscose Damper

The present study attempted to investigate the effect of viscose damper on the performance of 10 and 16- story structures. Data modeling was done based on PERFORM 3D software and energy absorption amount was examined in different modes through viscose dampers. To investigate the effects of the so called dampers on the seismic behavior of the structures, the performance of special moment frames with and without viscose damper with the protection power of 20% to 30% against earthquake damages was considered. Also, hysteresis diagram was studied. The research findings revealed an appropriate effect of viscose dampers on decreasing seismic effects of earthquake such that the structure with damper showed significant energy depreciation in comparison with the structure without damper and the damper with higher damping force plays a more effective role in increasing energy depreciation. Therefore, viscose dampers with higher damping percentage (30%) have a good capability to retrofit structures
