REAL TIME OSS-SSI TESTING METHOD

摘要：

This paper presents the implementation of a novel structural testing method involving the combined use of shake tables and computational engines for the seismic simulation of interaction of soil-structures under multi-dimensional and multi-support ground input motion. The structure with soil to be simulated is divided into experimental and computational substructures,in which structure is seen as experimental substructures and soil is seen as computational substructures. The interface reaction between the experimental and computational substructures are imposed by shake table as ground motion and resulting acceleration is fed back to the computational engine. The unique aspect of this method is to simulate the interaction of soilstructure under multi-dimensional and multi-support excitations. And then the sub structuring strategy and the numerical integration algorithms associated with the computational substructures are presented along with the implementation of the computational engine. Finally,an example of a real-time hybrid test implementation,and results from this experiment are presented.
