子结构拟动力试验平台NetSLabOSR开发与试验应用

摘要

In order to promote research and application of pseudo dynamic test method, a substructure pseudo dynamic test platform NetSLabOSR for building structures is developed to evaluate the seismic performance of structure engineering system. NetSLabOSR test platform includes three modules: ControlCtrOSR, Tester, ControlEqDAQ. The ActiveX control method based on the dynamic data link library is developed to realize the connection between the main module and the test equipment system, and complete transmission and conversion of substructure test data. The substructure pseudo dynamic tests are carried out using the NetSLabOSR test platform, in which the buckling restrained brace with inverted v⁃shaped and the concrete filled steel tube column are taken as test substructures. Through the research of pseudo dynamic tests, the seismic performance of composite frame structures is studied and the reliability and stability of NetSLabOSR test system platform are verified by substructure pseudo dynamic test results.%为推进拟动力试验方法的研究与应用，开发了子结构拟动力混合试验平台NetSLabOSR，可用于结构工程体系抗震性能的评估． NetSLabOSR试验平台包括3个模块：ControlCtrOSR，Tester和ControlEqDAQ．通过动态数据链接库开发的ActiveX控件方式实现各主模块与试验设备系统的连接，完成子结构拟动力试验试验数据之间的传递、转换．利用NetSLabOSR试验平台对子结构取倒V型防屈曲耗能支撑和钢管混凝土底柱的试验模型，进行子结构拟动力试验研究，试验结果验证了NetSLabOSR试验平台的可靠性和稳定性．
