3D 수치 모델링 기술을 활용한 종교시설 첨탑 안전성 점검 사례연구

A case study of safety inspection of the spire of a religious facility using 3D numerical modeling technology

Among religious facilities, the location of the steeple is often difficult or impossible for administrators or experts to check for safety, so it is a structure that is in the blind spot of management. In particular, the church steeple is classified as a structure, not a building, and is not included in structural review or permission, so it is operated without basic procedures to secure safety from the construction stage. As of 2021, there are 78,000 spires in religious facilities, and in the case of Seoul, there are more than 1,000 spires 6 meters tall or taller. In 2018, a spire fell on the road in Daegu and a passerby was injured, and in September 2019, a spire in Seoul fell to the roadside due to reeling with strong winds of 30 to 40 meters per second. However, it is difficult to visually determine whether a defect has occurred due to the difficulty of access by the inspector due to the installation location. In this study, 3D modeling technology using drones was applied to spires that are difficult to access, to check whether defects occur in areas that are difficult for inspectors to access, and if defects occur, model the size, area, and discoloration of the defect and then describe the modeling results technically This is an example of analysis.
