【摘要】 本文对纵向地震动输入下的渡槽结构地震响应进行主动控制数值模拟,比较了不同的设计参数的控制方案的控制效果,对渡槽的地震响应控制的作动器设置情况进行讨论,计算结果表明:渡槽结构加入控制装置对结构在地震作用下的响应有明显的控制作用,但是单纯的增加作动器的数量并不能达到与之相符的期望控制效果,对于渡槽结构的纵向振动控制,槽身间的控制装置对整体控制效果起到主导作用,研究结果对大型渡槽结构的抗震设计具有一定的参考价值。更多还原

【Abstract】 In this paper,numerical Simulation of active control for large scale aqueduct under longitudinal earthquake excitation was performed,control effects of several control schemes with different design parameters were compared,and the different positions of the actuators set were carried on the discussion. Results indicate that,setting actuators can efficiently reduce the aqueduct responses induced by earthquake, however,only increase the number of actuators can not achieve equivalent performance,the actuators between aqueduct bodies play a leading role in the vibration Control for aqueduct under Longitudinal Earthquake excitation.The results from the present study may serve as a reference base for seismic design of large-scale aqueducts.更多还原
