Abstract

As online commerce increases, the construction of large logistics buildings worldwide is exploding. Most of these buildings have the characteristics of long span and heavy loaded and use precast concrete components, a pin joint structure, for rapid construction. However, due to construction safety and structural stability requirements, the pin joint structure has many limitations in terms of the erection of the PC member, which increases the time and cost. A structural frame connected with steel joints between precast concrete components, called a SMART frame, has been developed, which addresses these constraints and risks. However, the effect of the appllication of a SMART frame on the time aspect has not been analysed. The study is a time reduction effect analysis of a SMART frame for long span and heavy loaded logistics buildings. For this study, the authors select a case site erected using existing PC components, and compare the time reduction with the SMART frame erection simulations. Through this analysis, it was found that a time reduciton about 4 months, approximately 48% of the conventional PC installation period could be achieved. If the SMART frame is applied when carrying out future large-scale logistics building projects, it can be expected to have the effect of significantly shortening the construction period compared to the conventional method.

인터넷 상거래가 증가함에 따라 전세계적으로 대형 물류 건물의 건설이 증가하고 있다. 이들 건축물은 대부분 장경간중재하의 특성을 가지고 있으며 빠른 시공을 위해 핀조인트 구조인 PC 공법을 적용한다. 그러나 핀조인트 구조는 시공 안전성 및 구조적 안정성으로 인해 PC 부재의 설치에 많은 제약이 있어 시간과 비용이 많이 소요된다. 이러한 제약과 문제점을 해결하기 위해 PC 부재 사이의 철골 조인트로 연결된 구조 프레임인 SMART frame이 개발되었다. SMART frame에 대한 많은 연구가 진행되었으나 공기 측면에 대한 영향은 분석되지 않았다. 본 연구의 목적은 장경간 중재하 물류창고시설에 대한 SMART frame의 공기단축 효과를 분석하는 것이다. 본 연구를 위해 기존 PC 공법에 의해 건설된 사례현장을 선정하여 SMART frame 설치 시뮬레이션과 시간 단축을 비교하였다. 그 결과, 기존 PC설치공기의 약48%의 수준으로 약 4개월이 단축 되었다. 추후 대형물류센터 프로젝트 진행 시 SMART frame을 적용한다면 기존 PC공법 대비 획기적인 공기단축의 효과를 가질 것으로 기대된다.
