Abstract

To expedite construction of small precast concrete buildings using dry joints, this study developed and evaluated a connector system for solid slabs. The research included a comprehensive literature review on seismic design requirements for precast concrete floors, followed by an analytical evaluation of the connector's bearing capacity in 3-story buildings. Experimental assessments were conducted to determine the in-plane and out-of-plane capacities of the newly designed semi-circular connector. Finally, the constructability of both the semi-circular and flat connector configurations was compared through tests on single-story precast concrete frames.

이 연구에서는 건식 프리캐스트 콘크리트 공법을 이용해 소형 건축물을 시공 효율을 높이기 위해서 솔리드 슬래브의 연결장치를 개발하였다. 프리캐스트 콘크리트 바닥에 대한 내진설계 요구사항 등을 조사하였고, 3층 소형 건축물의 프리캐스트 콘크리트 바닥 구조의 연결부에 작용하는 부재력을 해석적으로 평가하였다. 개발한 반원형 연결장치의 면내 및 면외 보유 내력을 실험적으로 평가하여 결과를 제시하였다. 단층 프리캐스트 콘크리트 골조를 대상으로 시험 적용을 통해 반원형과 평판형 연결장치의 시공성을 비교하였다.
