Construction duration of cast in place segmental bridges can be accelerated by using rapid hardening concrete, so that the jacking force can be given at earlier age. Jacking force raise high concentration stress in pre-stressing tendon anchorage zone, so that stress and deformation of the anchorage zone should be analyzed to confirm that nothing crack happened. Finite element method is one of the solutions to analyze this case. This study concerned bridge of Lemah Ireng II at Semarang - Solo highway (3-spans, 2-Piers). The anchorage zone of a bridge segment was numerically modelled by using nonlinear finite element solid 3D using Abaqus. This study to get information of stress distribution and concrete crack indication in anchorage zones due to the age of concrete jacking variation that take in 0.5, 1, 1.5, 2, and 3 days. FEA analyze of anchorage zone conclude that based on the stiffness, stress and crack contour distribution of anchorage zone, jacking force to the tendon anchorage can be approved at one day of concrete age. |
