摘　　要：近年来,智能驱动材料、控制装置和智能控制算法的研究和发展为土木工程的抗震控制开辟了新的天地。笔者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,并建立了量化因子、比例因子与结构响应之间的关系。对受控的3层基准建筑结构进行了非线性地震反应的数值仿真分析,并与其它的控制策略进行比较。结果表明,采用模糊控制算法,能有效抑制建筑结构的非线性地震反应,减少地震对建筑结构的破坏。Intelligent materials, control devices and intelligent control algorithm research and development in recent years have opened a new world for seismic resistance and disaster reduction in civil engineering. We designed and fabricated a new piezoelectric friction damper. In our research, we regarded the piezoelectric friction damper as the control device. We proposed a fuzzy control algorithm for reducing nonlinear seismic response of a 3-story benchmark building and established the interactive relationships between structural responses and fuzzifier factors, defuzzifier factor. A numerical simulation is carried out to analyze the nonlinear seismic responses of the controlled 3-story benchmark building. The simulation results are compared to those of other control strategies. The results show that the fuzzy control can reduce the nonlinear seismic response of 3-story benchmark building and minimize the structural damage caused by strong earthquakes.
