Taking OpenSEES as core computing platform , substructure pseudo-dynamic test method for frame structures is investigated , in which complex physical substructure is considered .Simulation method of complex boundary conditions is discussed when sub-frame is separated from global structure as physical substructure and thus the problem of OpenSEES blocked by remained geometrically unstable numerical substructure is solved .The feasibility and validity of the proposed substructure pseudo-dynamic test method are proved with two virtual tests , one is a 5-bay 12-story steel frame with buckling strained braces in which a 1-bay 1-story frame is separated as physical substructure , and the other is a 3-bay 8-story reinforced concrete frame with a 1-bay 3-story frame sub-structure .%以OpenSEES为核心计算平台,针对框架结构体系取复杂子结构的拟动力试验方法开展研究.探讨了取局部结构体系为试验子结构时的边界条件模拟方法,解决了数值子结构因形成几何可变体系而无法在OpenSEES中求解的问题.通过一榀十二层五跨防屈曲支撑钢框架结构和一榀八层三跨钢筋混凝土框架结构,取一层一跨和一层三跨结构体系为试验子结构的拟动力试验,验证了此子结构拟动力试验方法的可行性与有效性.
