Abstract

Apartment housings that adopt a bearing wall structure design, which account for a majority of the housing units available in Korea, are not free from structural constraints that limit the extension of their service life. The resulting need for reconstruction from the ground up requires a massive consumption of resources and energy, and triggers environmental pollution resulting from construction wastes. As a solution to such issues, the government enforces incentive schemes to promote a remodeling-friendly rahmen structure design. Green Frame, which is a novel concept of composite precast concrete structure to support rahmen structure apartment housing buildings, can address the constraints of bearing wall structure and conventional rahmen structure designs that limit the potential for remodeling projects, while reducing the term of construction. Therefore, this study aims to analyze the characteristics of Green Frame and its absolute term of construction, and compare the terms of frame work construction in apartment housing projects adopting different structural design approaches to illuminate their differences. In the end, Green Frame is found to be capable of reducing the term of construction in apartment housing projects. As the term of construction is a very critical element of a construction project, Green Frame will ultimately prove to be one of the key enablers to ensure the success of apartment housing construction projects.

현재 국내 주택의 근간을 이루는 내력벽식 공동주택은 구조적 한계로 인해 단수명화되고 있다. 이로 인해 발생하는 재건축은 막대한 자원 및 에너지 소비와 건설폐기물로 인한 환경오염을 유발하고 있다. 정부는 이러한 문제 해결의 방안으로 리모델링이 가능한 라멘구조를 유도하는 인센티브 제도를 시행하고 있다. 따라서 새로운 개념을 적용한 라멘구조의 공동주택을 위하여 개발된 복합PC구조인 Green Frame은 내력벽식 및 기존 라멘조식 공동주택이 리모 델링이 어렵다는 단점을 개선할 수 있을 뿐만 아니라 공사기간 단축이 가능할 것이다. 그러므로 본 연구에서는 Green Frame의 특성과 절대공기를 분석하고, 구조별 공동주택의 골조공사 공기와 비교 분석하여 차이점을 규명하였다. 그 결과 Green Frame을 공동주택에 적용할 경우 공기단축이 가능한 것으로 나타났다. 따라서 건설공사에서 공기는 매우 중요한 요소로 향후 성공적인 공동주택의 사업을 위해서 중요한 핵심기술로서의 역할을 할 수 있을 것으로 사료된다.
