A RATIONAL METHOD FOR DETERMINING PLACEMENT AND PERFORMANCE OF CONNECTING DAMPERS USING MULTI-MASS SHEAR MODELS

This paper proposes a method for finding the optimum damper placement which connect two buildings to reduce the seismic response of building structures. The proposed algorithm is simple iterative procedure to add small amount of damper into most effective story incrementally. The effectiveness of connecting damper is evaluated from maximum response in time range or the maximum value of transfer function. The validity of the proposed method is examined through numerical examples using multi-mass shear model considering maximum response in time and frequency range. Furthermore, the comparisons of solutions using multi-mass shear model and reduced one storied model have been conducted.
