커플러와 루프이음 방식을 적용한 프리캐스트 우각부 연결구조 성능 실험

초록

Recent study about near-surface urban transit is proposed to overcome uneconomical problem of underground subway. Development of construction technology using open-cut precast modular structure for main structure of the near-surface urban transit is under way. In this paper, performance test of corner rigid joint of the modular structure is carried out. Loop connection, and coupler connection is considered. As a result of the test, the structural performance of coupler connection is more advantageous. However, loop connection, considering effective construction, also satisfies the performance requirements.
