Abstract
Numerical analysis of shear walls governed by flexural behavior is conducted for the seismic control performance of proposed friction dampers installed at the center of coupling beams. Control effectiveness of shear walls connected by beams with the proposed dampers are compared for single shear wall with same flexural rigidity. Average responses of the shear walls with the dampers are found with seven scaled-downed earthquakes based on KEC 2005 design spectrum. Slip load is the most important design parameter. It is designed to be 5, 10, 20, 30, 60, 90% of total vertical shear force at damper location to prevent damper slip in specific stories. Nonlinear time-history analysis is conducted by using SeismoStruct analysis program. Seismic control performance of the dampers is evaluated for base shear, energy dissipation, curvature and top-floor displacement. Results show that the dampers are the most effective in reducing the responses when their total slip load is 30% of total vertical shear force.
