双向混合试验方法及验证
|
摘要
混合试验是一种重要的结构抗震试验方法。研究表明,地震对结构的作用是多向的,水平双向地震对结构的破坏作用比单向地震大很多。精确地完成双向混合试验对抗震研究具有重要意义。主要研究双向混合试验的加载控制方法。阐述了坐标转换方法及试件恢复力的求解方法,提出基于数值迭代算法的外环加载方法以及力控制的冗余作动器加载方法,数值模拟及真实试验表明本文所提出的加载控制策略具有较好的精度。
Hybrid test method is an important structural aseismic test one, and study shows that the action of earthquake on structures is often multi-directional, and horizontal bi-directional earthquake's destructive action on structures is much larger than unidirectional one's. Therefore, it makes sense to perform accurate bi-directional hybrid tests for anti-earthquake studying. Here, the loading control method for bi-directional hybrid tests was studied, and the coordinate transformation method and the one for solving specimens' restoring force were presented. An outer loop loading method based on the numerical iteration algorithm and the redundant actuator loading one for force control were proposed. Numerical simulation and actual tests showed that the proposed loading control strategies have a higher accuracy.
