Abstract

Green Frame was developed to embody a Green structural system that can provide long life, resource reduction, and availability of remodeling in apartment buildings. Composite precast concrete column and beam, the major structural material of Green Frame, can be installed precisely and promptly through connection of steels and concrete. The connection of Green Frame can be divided into four types, based on the method and characteristics of connection. To select an appropriate type for the site, a comparative analysis of the four types is necessary. The objective of this study is to compare the duration, cost, quality, and safety of four types. The findings of this study can be applied during the selection that appropriate composite precast concrete column reflected project characteristics in design phase.

공동주택의 리모델링 수월성, 장수명화, 자원저감, 친환경 구조시스템 구현을 위하여 라멘구조인 그린프레임 공법이 개발되었다 그린프레임의 주요 구조부재인 합성 프리캐스트 콘크리트 기둥과 보는 접합부 철골과 콘크리트에 의한 접합으로 신속하고 정밀하게 설치할 수 있다. 그린프레임의 접합부는 그 형상에 따라 네 종류로 분류할 수 있으며, 각 종류에 따라 각기 접합 특성과 시공방법이 다르다. 현장상황에 적합한 기둥을 선택하기 위해서는 기둥 종류별 접합부 특성 비교 연구가 필요하다. 따라서 본 연구에서는 기둥 종류별 접합부의 공기, 원가, 품질, 안전성능 비교 분석하는 것을 목적으로 한다. 본 연구의 결과는 GF 공법의 설계단계에서 프로젝트 특성을 반영한 적정 합성 프리캐스트 콘크리트 기둥을 선정하는데 활용된다.
