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。
In recent years, the research and development of intelligent drive materials, control devices and intelligent control algorithms have opened up a new world for the seismic control of civil engineering. A new piezoelectric variable friction damper was designed and manufactured by the author. As a control device, a fuzzy control algorithm that can effectively restrain the nonlinear response of high-rise buildings under strong earthquake excitation was proposed. The quantization factor, scale factor Relationship with structural response. The numerical simulation of the nonlinear seismic response of the controlled three-story reference building structure is carried out and compared with other control strategies. The results show that the fuzzy control algorithm can effectively suppress the nonlinear seismic response of the building structure and reduce the damage to the building structure caused by the earthquake.
