Analysis of Elasto-Plastic Behavior of Concrete-Filled Steel Tubular Beam-Columns Falling in Local Buckling Tsuiki, Akira 築城, 彰良 Kawaguchi, Jun 川口, 淳 Morino, Shosuke 森野, 捷輔 Stress degradation Stress-strain relation Moment-curvature paths Beam-column Elasto-plastic analysis Hysteresis loop application/pdf Elasto-plastic and post-buckling analysis was performed to trace the cyclic behavior of concrete-filled steel tubular (CFT) beam-columns, which had been tested previously. Analytical model to solve the deflections of the beam-column was divided into a number of elements, and the solution satisfying the equilibrium at each subdivision point was searched by the proposed way of combining the degrading type moment-curvature relation with the numerical integration scheme. The effect of local buckling of steel tube was taken into account by employing the degrading type of stress-strain relation. The paper first presents how to handle the deflection analysis of a member whose moment-curvature relation possesses the descending part, which is not possible by the conventional numerical integration, and discusses the accuracy of the solution compared with the test results. departmental bulletin paper Faculty of Engineering, Mie University 1998-12-25 VoR application/pdf Research reports of the Faculty of Engineering, Mie University 23 39 50 0385-6208 AA00816341 https://mie-u.repo.nii.ac.jp/record/5037/files/AA008163410230007.PDF http://hdl.handle.net/10076/4059 https://mie-u.repo.nii.ac.jp/records/5037 eng
