The purpose of this paper is to determine the optimal placement of MR dampers for the vibration control of building structures. The dynamic characteristics of Bingham model, Simple Bouc-Wen model, Simple Bouc•Wen model with Mass Element and Spencer model for the modeling of MR dampers, were investigated. By performing the numerical analysis of SDOF system excited by harmonic, white noise, and seismic load, the type and amplitude of excitation which are important design factors of MR dampers were considered. Finally, Four cases for placement of MR dampers installed at 20-story building structure were considered and the corresponding results indicate that the case installing MR dampers sequentially at the story with maximum inter-story drifts provides the best performance.
