Abstract

Buildings that have been long neglected can suffer severe durability reduction due to factors such as rebar rust and concrete quality deterioration resulting from exposure to outside air. Furthermore, the issues associated with these suspended buildings, including safety accidents, social crimes, and environmental pollution, are becoming increasingly serious. This study investigates the current status of these buildings in the Jeju area, identifies the problems, and examines the durability of the structure in a specific location to assess the possibility of future use. Aesthetic surveys(visual and slope inspections) as well as non-destructive tests(compressive strength tests, neutralization tests, and rebar detection tests) were conducted to assess durability. The analysis revealed that the structure maintained satisfactory durability and the building's condition was good in comparison to the years of neglect.

장기방치된 공사중단 건축물들은 외기의 노출로 인한 철근의 녹 발생, 콘크리트의 품질 저하 등으로 건축물의 내구성이 심각하게 저하될 수 있으며, 관리부실로 안전사고, 사회적 범죄 발생, 환경오염 등 공사중단 건축물에 대한 심각성이 커지고 있다. 본 연구는 제주 지역의 공사중단 건축물의 현황을 조사하고 문제점을 파악하고, 1곳에 대해 구조체의 내구성을 조사분석하여 사용가능성을 진단하였다. 내구성 조사를 위해 외관조사(육안조사, 기울기조사)와 비파괴검사(압축강도시험, 탄산화조사시험, 철근탐사시험)이 진행되었으며, 구조체가 내구성을 갖추고 있으며 건축물의 상태는 경과년수에 비하여 양호한 것으로 분석되었다.
