Abstract: “This study analytically investigates the seismic behaviour of post-tensioned precast segmental columns comparing with conventional monolithic bridge columns. For this purpose, 3D nonlinear finite element ANSYS software is employed. In this study, the numerical results of quasi-static analysis are compared and validated with the experimental results. Then, the behavior of the column samples of monolithic conventional and precast segmental are compared under lateral cyclic loading. The nonlinear-static analysis shows that the precast segmental bridge sample compared to the monolithic column has higher stiffness with negligible residual displacement.”
