초록

최근 건축물의 품질과 안전관련 문제가 증가하면서, OSC(Off- Site Construction) 구조에 대한 연구가 많이 진행되고 있다. 이러한 연구 중 하나의 결과로 OSC 구조부재로서 패널라이징 합성보인 KG보가 개발되었다. KG보는 ㄷ형강을 사용한 U형 합성보로서, 데크플레이트를 KG보에 공장에서 사전 용접하고 현장에서 볼트 체결을 한 후, 콘크리트를 타설함으로써 보-슬래브 바닥시스템이 형성된다. 이 연구에서는 외다이어프램 형식의 CFT기둥-패널라이징 합성보(KG보) 엔드플레이트 접합부를 제안하고, 이 접합부의 내진 성능을 실험적으로 평가하였다. 실험결과, 제안된 접합부의 회전성능은 강구조 설계기준의 합성중간모멘트골조 요구회전각 0.03 rad.을 충분히 만족하였다.

Abstract

Recently, as the issues related to the quality and safety of buildings have increased, many researches on off-site construction (OSC) structures have been conducted. As a result of one of these researches, a panelized composite beam, KG beam, was developed as an OSC structural member. KG beam is a U-shaped composite beam using channel. The deck plate is pre-welded to the KG beam at the factory, bolted on site, and then concrete is poured to form a beam-slab floor system. In this study, the external diaphragm type end-plate connection between CFT column and panelized composite beam (KG beam) was proposed and the seismic performance of this connection was experimentally evaluated. The test results showed that the rotational capacity of the proposed connection sufficiently satisfies the required rotation angle of 0.03 rad. for composite intermediate moment frame in the design code for steel structures.
