Development and experimental application of substructure pseudo dynamic test platform NetSLabOSR

Abstract:

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.
