随着建筑形式的多样化以及结构高度、跨度的增大,结构在地震和风等动力荷载作用下的振动问题也日益突出,智能材料的研究与应用成为结构抗震控制技术领域最具前沿性的发展方向之一.本文根据主动控制力学模型,基于最小储能原则,运用遗传算法,得到了主动杆件的最优布置位置和最优增益;进行了三层空间结构主动抗震控制实验,研究结果表明,压电主动杆的控制效果与输入地震波的关系不大,而与结构自身参数关系密切,对结构进行智能控制之后抗震效果显著,结构各层的位移最大抑制达到14%,加速度的最大抑制达到21%.

Teeming with large-span and complex structure, the structure vibration problem has become more promi-nent under load, such as earthquake and wind power. The application of intelligent materials and smart structure is becoming one of the most cutting-edge work in the structure field. Based on the active control mechanical model and the principle of minimum energy, according to the genetic algorithms we optimized the layout of the driving le-ver and the minimum gain. Then an active control experiment for a three-storey intelligence spacial structure was done. The research shows, the control effects is not related to the input seismic ground motions, but closely related to the structure parameters. The intelligent structures can produce greatly inhibitive effects. The maximum displacement reduces 14% , and the maximum acceleration reduces 21%.
