框-剪偏心结构平-扭耦联反应半主动控制试验研究
|
摘要
针对采用磁流变阻尼器(MRD)控制框架-剪力墙偏心结构在地震作用下的平-扭耦联反应,基于Matlab/Simulink软件平台和dSPACE实时仿真系统进行模拟地震振动台试验,分别验证结构在不同地震动输入下被动控制方式和半主动控制系统的有效性.试验结果表明:结构水平及扭转地震反应均能得到显著降低;被动控制对地震动输入较为敏感,而半主动控制的效果要优于被动控制;MRD的位置对控制效果具有重要影响.
The experimental system of frame-shear wall eccentric structure was built according to the coupled translation and torsion response control of this structural model using magnetorheological damper(MRD),and then the shaking table experiment of the structural model is implemented based on Matlab/Simulink software environment and hardware/software resources of dSPACE.The validity of two passive control strategies and the semi-active control strategy is verified under three input earthquake excitations with different peak values.The experimental results show that the coupled translation and torsion response is significantly mitigated,and the semi-active control strategy can achieve higher performance levels as compared to those of the two passive control strategies.Moreover,the location of the MRD has an important effect on the control results.
