DEVELOPMENT OF A REMOTE HYBRID TESTING PLATFORM FOR BRIDGE STRUCTURES
A distributed hybrid testing platform for remotely collaborative pseudo dynamic (hybrid) test of bridge structures has been developed in this paper. The platform consists of four types of modules, namely ControlCtr, PhysicalTester, VirtualTester, and Observer. ControlCtr organizes the testing procedure, coordinates data communication, and handles numerical integration of entire structure. PhysicalTester and VirtualTester generate restoring forces of substructures by operating testing facilities and computing resources respectively. Observer accepts testing results from ControlCtr and stores them in a database for publishing on web. The across middleboxes data transfer among geographically distributed laboratories is achieved by using the network based communication platform established by the authors for developing networked structural laboratories (NetSLab) system. A standard ActiveX control, developed in the structural laboratory of Hunan University, is utilized to transfer control signal and feedback data between PhysicalTester and MTS electro-hydraulic servo system. Using the testing platform, hybrid tests of bridge structures under different levels of earthquake excitations were carded out. The results show that the platform is feasible for seismic performance simulation of bridge structures in a remotely collaborative manner.
