Abstract |
Post-tensioned precast concrete system(PPS) consists of U-shaped precast wide beams and concrete column. The continuity of beam-column joint is provided with the topping concrete??on the PC shell beam and post-tensioning. The purpose of this paper is to evaluate the response of PPS interior beam- column joint subjected to cyclic lateral loading. To this end, the experimental investigation was performed with three half-scale specimens of interior connection. The design parameter is the beam width ratio to column width. The test results showed that specimen cracks were distributed well and plastic hinges spread toward midspan without any significant degradation of strength and ductility. And the specimens sufficiently resisted up to the limiting drift ratio of 0.035 of the provisional by ACI of acceptance criteria for concrete special moment frames. |
