Analytical and Experimental Modeling Accuracy

In this study, numerical accuracies due to element size in the region near supporting gigue in the lon­gitudinal direction, yield criterion for concrete material, system damping constant were investigated from the viewpoint of wave configuration of response. Numerical accuracies should be investigated for not only each parameter but also interaction between each two parameters considered here. However, those investigations need too much computation time. Then, here, the accuracy was invest­igated for each parameter considered here based on the finally determined input data by conducting preliminary analysis.
