강선 이음형 PC 보-기둥 내부 접합부의 구조적 거동에 관한 실험적 연구 = An Experimental Study of the Structural Behavior on the PC Beam-Column Interior Joint with Strand

다국어 초록 (Multilingual 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 9.3㎜, 7strand for reinforcement. Fore specimens for partial tension test and three specimens for beam-column interior 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 was transverse reinforcement in 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.
