| Research Abstract |
Loading test was conducted with eight damaged precast concrete columns post-tensioned by PT tendons after retrofitting, in order to investigate their structural performance such as initial stiffness and flexural capacity. The experimental parameters were retrofitting method, type of PT tendon and damage level. Discussion about the effect of retrofit and experimental parameters on the structural performance was carried out by comparing the experimental data obtained before and after retrofit.
