- Abstract:
- To reduce the influence of large scale on the structural performance,and accurately simulate the connection of assembled structure,relevant structural measures and dynamic response of non-structural components are the key problems to be solved in the development of experimental technology.The shaking-table real-time hybrid simulation provides the possibility to solve the problems existing in the testing and research of structure resilience and disaster prevention.This paper briefly discusses the potential needs of shaking-table real-time hybrid simulation test in structure resilience and disaster prevention,as well as the key technical problems to be solved to achieve the relevant needs.The research results show that the real-time hybrid simulation can indirectly increase the test capacity of the shaking table by combining the numerical simulation and physical test,which has the advantages of increasing the physical test size and reducing the size effect.However,there is still a need for further research on numerical substructure calculation efficiency,stability analysis of test system,physical loading accuracy,numerical substructure modeling accuracy and boundary condition model.
