Abstract
최근 막 구조물의 수요 증가에 따라 막 구조물의 구조 및 재료적 연구의 진행은 막 구조물을 하나의 독립된 구조물로써 인정받을 만큼 활발히 진행되고 있지만, 유지 관리 측면의 연구의 경우 아직까지 이에 미치지 못한 상황이다. 특히 유지관리 측면에의 연구 중 지붕구조의 수밀성 및 누수에 관한 연구는 해외에서 일부만을 다루고 있어 국내 실정에 맞는 유지관리 지표 개발이 요구되고 있다. 이에 본 연구에서는 막 구조물 지붕부의 막재 및 접합부, 지붕 형태에 따른 누수취약부에 대해서의 하자 사례 조사를 통하여 누수 요인 및 열화 인자를 분석하였고, 이를 AHP기법을 활용하여 중요도를 부여하여, 막 구조물에서 필요한 유지관리 지표를 제안하였으며, 이를 바탕으로 막 구조물 지붕의 장기적으로 수밀성 확보를 위한 설계 및 시공단계서의 수밀성 평가 지표, 준공 후 사용과정에서의 점검 관리 지표를 제안하였다. With the increased demand for membrane structures in recent years, there have been many studies of their mechanical properties, to the extent that such structures have become recognized as independent structures with a level of safety and durability comparable to those of other general structures. But in reality, the study for the maintenance of membrane structures has not been as active. In particularly, the study of watertightness from the perspective of maintenance has been very limited. Accordingly, a study on securing watertightness performance and the guidelines for maintenance is necessary. In this study, through a case study of water leakage accidents in membrane structures overseas, causes of leakage were selected from the membrane material itself, joint parts and open door of roof part in membrane structure. The water leakage and deterioration elements were analyzed from those leakage causes. The degree of importance of the water leakage and deterioration index was also designated using the AHP (Analytic Hierarchy Process) method. As a result, the basic technical index was suggested for the maintenance of the roofs of large-span membrane structures to prevent water leakage. This index will be used to make a guideline for the long-term maintenance of the roofs of large-span membrane structures.
