压电变摩擦阻尼器对高层建筑非线性地震反应的模糊控制算法
|
摘要
设计制作了一款新型的压电变摩擦阻尼器,并将其作为控制装置,提出了能有效抑制强烈地震激励下高层建筑结构非线性反应的模糊控制算法,通过模糊控制算法建立了施加在压电变摩擦阻尼器上的电压与结构的响应之间的关系。对一个受控的20层基准建筑结构进行了非线性地震反应的数值仿真分析,并与别的控制策略进行比较。结果表明,对于安装有压电变摩擦阻尼器的结构,采用模糊控制算法,能有效抑制高层建筑结构的非线性地震反应,减少地震对建筑结构的破坏。
For reducing nonlinear seismic response of high-rise buildings,a newly designed piezoelectric friction damper was adopted as control device,and a fuzzy control algorithm was proposed.Interactive relationship between struc- tural response and input voltage of piezoelectric friction dampers was established by using a fuzzy controller.Numerical simulation was carried out for analyzing the nonlinear seismic responses of the controlled 20-story benchmark building,and the results were compared with those by other control strategies.The results show that the fuzzy control with piezoelectric friction dampers can reduce the nonlinear seismic response of high-rise building efficiently and minimize the damage in the building structures caused by strong earthquake.
