Sponsored by the National Natural Science Foundation under the National Key Project"The modern method and system for remote pseudo dynamic testing of structures under earthquake simulation"(50338020), some studies on the method for remotely collaborative hybrid dynamic testing of substructures and structural elements have been carried out in this thesis. The main research achievements are summarized as followings: Based on the network communication platform NetSLab (Networked Structural laboratories) developed by the research group, the rational framework of a platform for remote pseudo dynamic testing applications of substructures and structural elements is proposed and a robust standardized platform entitled NetSLab-SDOF has been developed for remotely collaborative hybrid dynamic testing of single story structures with Visual Basic program language. It is composed of four modules, named as control center, physical tester, virtual tester, and remote observer.
