摘要
混合试验是一种将数值计算和试验相结合的试验方法,其中数值子结构与试验子结构的合理划分是混合试验顺利开展的前提。为更准确地模拟实际地震作用下结构的响应,同时适应建筑规模化和复杂化的发展趋势,开展大规模足尺双向混合试验势在必行。设计了六层足尺钢框架双向混合试验,通过HyTest双数值子结构联机模拟代替数值子结构和试验子结构联机试验,并与原型结构的时程分析结果进行了对比,验证了数值子结构和试验子结构划分的合理性,同时也验证了HyTest开展大规模足尺双向多自由度混合试验能力。
Hybrid testing is a kind of test method which combines numerical calculation with physical experiment, and the division of numerical substructure and experimental substructure is the key for hybrid testing. In order to more accurately simulate the actual seismic response of structures, and to adapt to the trend of building which becoming large and complex, large scale bi-directional hybrid testing need to be applied. In this paper, a bi-directional hybrid test of six-story full-scale steel frame is designed, and the online simulation of HyTest for bi-numerical substructure is used to replace the numerical substructure and experimental substructure online testing. Finally, the results of online simulation were compared with the time history analysis results of the prototype structure, and the rationality of the division of the numerical substructure and experimental substructure is verified, then it is also verified that HyTest has the ability to carry out hybrid testing which is large-scale, bi-directional and multi-multi-degree bffreedom.
