摘　　要：SRT混合仿真试验方法是在子结构混合仿真试验基础上进一步发展而来的一种新型抗震试验方法.介绍了SRT混合仿真试验方法的系统组成及原理,并以一个单层钢结构为原型,进行了空间SRT混合仿真试验.得到了不同工况下该结构各部位的时程曲线,通过试验数据的对比对试验精度和稳定性进行了系统的分析.结果表明作动器动态性能调试技术、实时补偿技术和地震激励的大小对加载的精度及稳定性有较大的影响.The SRT hybrid simulation test method is a new type of seismic test method based on the substructure hybrid simulationexperiment’s further development. The paper introduces the system composition and the principle of SRT hybrid simulation testmethod. With a monolayer steel structure as the prototype, the space SRT hybrid simulation experiment was carried out, and the timehistory curve of the different parts of this structure under different working conditions is obtained. By comparison with experimentaldata of system ,the test precision and stability is analyzed. Results show that the actuator dynamic performance debugging technology,real-time compensation technology, and the size of the earthquake excitation exert greater influence on the precision and stability ofthe load.
