【Abstract】 A SRT(Soft Real Time) hybrid simulation test system was proposed, consisting of the MTS electro-hydraulic servo system, the target computer with predictor-corrector function, OpenSees finite element software, OpenFresco interface software, and etc. The SRT hybrid simulation experiment was carried out, based on a space steel frame structure, while the experimental substructure(test specimen) was under real-time loading along the spatial x, y bidirectional. The experimental results show that the hybrid simulation test system, with good stability and accuracy, could work well to conduct SRT hybrid simulation tests of space structures.更多还原
