PRELIMINARY STUDY ON FINITE ELEMENT SIMULATION OF STEELASPHALT COMPOSITE ISOLATION LAYER
Finite element model of reinforced-asphalt composite isolation layer which considering influence of the asphalt ointment and brick piers is presented on the basis of shaking table test in this paper.Subroutine UBEAM is programmed to simulate the nonlinear characters of the steel bars under strong earthquakes; Subroutine USPRNG(nonlinear spring) is programmed to simulate the nonlinear interaction between the brick pier and the upper beam in the earthquake.Based on this calculation model,modes of each specimen of the shaking table test were calculated,a 3D model time history analysis is taken to simulate each shaking table test conditions.The calculated results are compared to the experimental results to verify the accuracy of the calculation model.
