Abstract:
Supplemental passive dampers are generally considered as an effective tool to control the seismic response of multi-storey buildings. Since the optimum placement of passive dampers in buildings can potentially improve the structural performance or reduce construction cost, there is an increasing number of researchers engaged to optimize the damper placement in buildings. Given that a large number of studies have been conducted to investigate damper placement methods, a systematic method or a clear conclusion for strategically distributing dampers in buildings is not presented in any building guidelines. The main limitations of current damper placement studies may include the lack of focus on collapse resistance of retrofitted buildings, on beam and column nonlinear behaviors, and the lack of considering the variations of earthquake characteristics and intensity levels. The fundamental damper placement issue can be separated as the distribution of dampers throughout the height of the buildings and the distribution of dampers in different bays in building frames. In this research, both distributions are explored and their effect on the collapse performances of buildings under strong earthquakes is thoroughly studied. The effectiveness of advanced damper placement approaches is evaluated by comparisons with classical damper placement methods. Considering the uncertainty in earthquake ground motion characteristics, multiple ground motions scaled to various intensity levels are involved to evaluate the seismic performance of buildings. Finally, major conclusions towards the philosophy of the strategic damper placement in practical building constructions are presented in terms of the overall structural performance under strong ground motions.
