RESEARCH ON THE SIMULATED TECHNIQUE OF COMPLICATED BOUNDARY CONDITIONS IN HYBRID TEST

摘要

In order to solve the difficulties in giant structure seismic test, the hybrid test idea is proposed, which combines actuators and shaking table. In this new test method, it is very important how to simulate the boundary conditions between the test substructure and analysis substructure. Two simulation methods and corresponding dynamic equations are provided in this paper. They are all based on the dynamic substructure analysis technique, such as DOF condensation, mode synthesis, constrained mode and so on. The merit and shortage of each method is discussed.
