多自由度等效力控制拟动力子结构试验研究

EQUIVALENT FORCE CONTROL SUBSTRUCTURE PSEUDO-DYNAMIC EXPERIMENTAL STUDY ON A MDOF MODEL

该文以三层框支配筋砌块短肢砌体剪力墙子结构足尺模型为基础,将等效力控制方法应用到试验子结构为多自由度结构模型的拟动力子结构试验中,通过数值模拟和试验结果,表明该方法具有很好的鲁棒性,可以完成试验子结构为多自由度复杂试验模型的拟动力子结构试验。

based on the full-scale three-storey flame-supported reinforced concrete short-leg masonry shear wall substructure test model, this paper applied the equivalent force control（EFC） method to the substructure pseudo-dynamic test for the physical substructure model, a multi-degree of freedom（MDOF） structural system. The feasibility of the EFC method for the physical substructure model, a MDOF system have been demonstrated with the numerical simulations and the testing results of the full-scale test model.
