| چکیده | ||
| In recent years, it is considerably attempted to develop the concept of energy dissipation as an applicable technology to overcome the energy released by earthquakes. The passive control systems such as metallic dampers have been widely considered. Energy dissipating dampers are used to modify the response of structures as well as to reduce the damages in structure members. This study is conducted to investigate the seismic response of three normal concrete moment resisting frames with 4, 7 and 10 stories equipped with Triangular Added Damping and Stiffness (TADAS) metallic dampers. OpenSees software is employed for nonlinear time-history analysis using seven earthquke records to determine the structure response. The results showed the considerable modifed seismic responses. It is observed that the story drifts are constant and the maximum values in retrofitted 4, 7 and 10 story frames have been decreased 54%, 56% and 55%, respectively. Also, the maximum floor acceleration, the maximum roof displacement and the maximum story shears are lower in the frames equipped with damper and the lateral behavior of the majority of the retrofitted frame members has been upgraded to Immediate Occupancy (IO) and Live Saftey (LS) performance level. | ||
