摘要
该文研究了建筑结构地震反应的半主动摩擦阻尼局域反馈控制问题。首先建立了安装有摩擦阻尼器的建筑结构的受控运动方程,提出了抑制结构地震反应的局域反馈控制方法。基于Kalman滤波提出了三种局域反馈半主动控制策略。通过数值研究考察了半主动摩擦阻尼器对建筑结构地震反应的控制效果,并进行了相应的参数研究。研究表明:该文提出的局域反馈控制策略可以有效地实现结构的地震反应控制。
The local feedback control of building structures using semi-active friction dampers subjected to strong seismic excitations is investigated in this study. The equation of motion of the controlled building is established and a local feedback control approach is developed for seismic mitigation. Three prediction feedback control strategies are proposed for the vibration control based on Kalman filter. The control performance is numerically examined with corresponding parameter investigations. The observations demonstrate that the proposed control approaches are effective for the response suppression of building structures subjected to different seismic excitations.
