Abstract
The PC-Mild-Press joint method is one of the methods which can control damage of structures with concrete. Authors have already carried out study and have clarified its mechanical behavior and damage. However, the effects of the floor slab on the structural behavior of the frame have not been clarified. In this study, experiments were conducted on a cruciform frame with a floor slab constructed by the PC-Mild-Press Joint method to determine its mechanical behavior and damage. The study focused on the effects of damage control when an prestress force was introduced into the floor slab using unbonded prestressing bars for the main floor slab reinforcement. The evaluation of damage in the floor slab derived from the crack width and the section analysis of interface's M-θ are proposed.
