Abstract |
In this study, new moment-resisting precast concrete beam-column joint is proposed for moderate seismic regions. it is attempt to devise connection detail which makes workability improve and confirm effective stress transfer in the region of connection. It has the connection details which help working process simplified and construction cost reduced as replace 9.3mm, 7strand for reinforcement. Two specimens for beam-column exterior joint test were producted. An experimental study was carried out to investigate the joint behavior subjected to reverse cyclic loading and constant axial compressive load. The test variables were a number of strand in connection which transfers stress in the beam. Structural performance of exterior joint is evaluated on the basis of connection strength, stiffness, energy dissipation,??drift capacity and strain gage. 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. |
