Abstract |
In this study, new moment-resisting precast concrete beam-column joint is proposed for moderate seismic regions. It has the splice type reinforcing bars, penetrated the joint and lap-spliced with the bottom bars of precast U-beam. An experimental study was carried out to investigate the joint behavior subjected to reverse cyclic loading and constant axial compressive load. Three precast beam-column interior were tested. The variables examined were the diameter of splice type reinforcing bar and the presence of transverse reinforcement in the joint. Structural performance of joint is evaluated on the basis of connection strength, stiffness, energy dissipation, and drift capacity. Based on the test results, the precast connection is 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. |
