数値震動台によるCFT柱の繰り返し曲げせん断解析のV&V

抄録

In this paper, cyclic shear-bending analysis of concrete-filled-tube (CFT) column using E-Simulator, which is a large-scale detailed finite element analysis system developed by NIED, is verified and validated. The solid element mesh is verified by varying types and sizes of solid elements. The effects of element types and sizes on analytical results are discussed. Two cases of experiment under variable axial load are simulated for validation. By comparing analytical and experimental results, it is shown that, the cyclic shear-bending behaviors are reproduced by E-Simulator. The computed internal damage of filled concrete is visualized and discussed.
