| Abstract |
The use of precast concrete structural system has been limited primarily to non-seismic areas. To promote the use of precast concrete in seismic areas, an adequate connection methods between precast members need to be developed and they must have enough strength and ductility. In this study, three types of anchorage detail were proposed for precast concrete exterior beam-column joint using half precast U-beam and precast column. An experimental study was carried out to investigate the joint behavior subjected to reverse cyclic loading with constant axial compressive load. Three precast exterior beam-column joint specimens were tested. Within the joint core, bars bent 90 degrees, bars bent 180 degrees, and bars having plane U shape were the main parameters for this experiment. Joint performance was evaluated on the basis of connection strength, stiffness, energy dissipation, and drift capacity. Test results show that the three types of connection detail provide the sufficient moment-resisting behavior and anchorage performance to be applicable for moderate seismic regions. |
