Research about Numerical Integration Method for Structural Dynamic Response in Real Time on-Line Test

Abstract:

The modified equations for PC-Newmark method and OS (operator-splitting) method were derived, which could be applied to the numerical solution for the non-linear equation encountered in real time on-line test. The structure with FPS seismic isolation system was divided into three substructures, namely the FPS system, the experiment substructure and the computation substructure. The explicit algorithm is applied to the first two substructures and the implicit algorithm to the third one in order to loosen the stability limitation. The numerical solution for a 7 DOF structural model has proven the alleviation for stability requirement.
