粘弹性阻尼器控制高层建筑地震响应的研究

Research on Seismic Response of High-rise Buildings with Added Viscoelastic Dampers

用拟力实模态叠加法对粘弹性阻尼器控制下的高层建筑地震响应进行了分析，依据最优耗能原则，确定了粘弹性阻尼器在建筑中的最优位置。编制了时程分析程序，以算例验证了粘弹性阻尼器对高层建筑地震响应控制的有效性和最优位置的合理性。

A modal superpostion pseudo - foroe (PF) is adapted to analyze seismic response of high - rise buildings with added viscoelastic dampers (VE). Based on the optimal energy- dissipation principle, a procedure to find the optimal locations of VE is developed. Numerical examles are presented to demonstrate the seismic performance enhancement by adding VE to structures and the feasibility of the optimal locations.
