摘　　要：抗震混合试验技术是一种基于子结构试验技术,结合有限元分析,将结构模型分为计算单元和试验单元,并将试验单元作为一种特殊的计算单元,通过不同类型单元间集成与组合,形成新型结构抗震试验方法。本文应用OpenFresco平台,实现了MTS793试验系统与OpenSees软件的数据交互,建立了基于OpenFresco的验证抗震混合试验系统,并进行了单榀框架的混合试验,将混合试验得到的位移时程曲线与OpenSees分析结果进行了对比,研究表明,该试验结果与有限元模拟结果基本一致,说明本文提出的应用OpenFresco平台的抗震混合试验技术满足结构抗震试验的要求。The method of hybrid simulation which combines the numerical analysis with the physical testing is the advanced form of existing structure experimental techniques. Especially, regarding the physical testing models as a special portion, which can be embedded in the numerical model, hence, hybrid simulation also can be considered as a novel analysis. In this paper, with the OpenFreseo software architecture, we developed the hybrid simulation system which achieved the data exchange between MTS 793 system and OpenSees. In order to study the stability of this testing technology, a hybrid simulation of a single-story portal frame was conducted, the comparison between the experimental results and numerical results shows that the hybrid simulation testing technology presented in this paper satisfies the requirement of structure seismic test.
