摘要

等效力控制方法用反馈控制求解拟动力试验隐式逐步积分方法的非线性方程,避免了复杂耗时的迭代过程。这篇文章成功应用等效力控制方法完成了以连梁阻尼器为试件的拟动力子结构试验,检验了其对双肢剪力墙结构的减震效果。这篇文章介绍了等效力控制方法原理和一些关键参数的选取方法,介绍了装有连梁阻尼器的双肢剪力墙结构模型,并对此结构模型进行了拟动力子结构试验。研究结果表明:通过合理选取等效力控制器和力-位移转换系数,等效力控制方法具有很好的稳定性和精度;连梁阻尼器对双肢剪力墙结构反应有很好的控制效果。

Abstract

The equivalent force control method (EFCM) replaces numerical iteration with feedback control strategy to solve the nonlinear equations of motion for real-time substructure testing with implicit integration method. This paper successfully applies the EFCM for the pseudo-dynamic substructure tests of coupled shear wall structure with coupling beam damper specimen in order to investigate the seismic performance of the structure. The EFCM and the determination of some key elements in EFC were introduced, and the simplified model and pseudo-dynamic tests of the coupled shear wall structure with coupling beam damper were presented. It is shown that the EFCM can achieve excellent performance in terms of stability and accuracy if the equivalent force controller and force-displacement conversion factor were properly designed, and the coupling beam damper can effectively control the seismic response of the coupled shear wall.
