| Abstract |
In this study, new moment-resisting precast concrete beam and column joint system is proposed for the use in moderate seismic regions. It is attempted to devise connection details which improve workability and provide effective stress transfer mechanism in the region of connection. The interior beam and column connection is made of U-shaped reinforced beam and 7-wire strands which are embedded in the bottom part of half PC beam. The experimental study was carried out to investigate the behavior of the interior joint subjected to reverse cyclic loading and constant axial compressive load. The test variables were the number of strands and transverse reinforcements in connection. Structural performance of interior joint is evaluated on the basis of connection strength, stiffness, energy dissipation, and drift capacity. Based on the test results, the precast connection is proved to be capable of matching or exceeding the performance of the monolithic connection and thereby provides the sufficient moment-resisting behavior to be applicable for moderate seismic regions. |
