弯剪型高层框架MR阻尼器的半主动控制

member model was established for a high-rise frame, and a shear-bending layer model was established by using static condensation method. By applying the strategy of semi-active control based-on LQR algorithm, seismic response and controlled effects of a ten-layer frame under different seismic wave (El-Centro wave, Taft wave and Tianjin wave) was numerically simulated and the results were systematically analyzed. The results shows that the seismic response of shear-bending high-rise building can be effectively reduced by using LQR strategy.
