介绍了磁流变阻尼器的性能及恢复力模型,提出了两种简易可行的半主动控制策略.三层框架结构的地震反应分析表明,策略2优于策略1和被动控制,该控制方法能够有效减小结构的地震反应.
The performance and the restoring force model of MR damper are introduced and two simple and feasible semi-active control strategies are proposed.Seismic response analysis of three-tier frame structure shows that strategy 2 is superior to strategy 1 and passive control, and the control method can Effectively reduce the seismic response of the structure.
