The models analyzed are a simple steel box and a steel box reinforced by the stiffener. The results of FEM analysis are compared with those of the experiments under the same condition. As a result, the following findings are obtained. 1. The effect of material stress-strain relationship on the results of FEM analysis is evident. The comparison of the case using kinematic hardening rule with the case of isotropic hardening rule shows that kinematic hardening rule qualitatively gives better results than isotropic hardening rule regarding the shape of hysteresis loop and maximum load carrying capacity. 2.It is possible to evaluate qualitatively the process starting from local buckling and reaching maximum load carrying capacity., 長崎大学工学部研究報告 Vol.27(49) p. 247-252, 1997}, pages = {247--252}, title = {弾塑性有限変形解析による鋼製箱型橋脚載荷実験のシミュレーション解析}, volume = {27}, year = {1997} }
