Abstract

The Crack, occurred in the concrete structure, is a major cause of function deterioration such as strength, durability and waterproof. Therefore the need for crack reduction will continue as long as there is concrete structure. But, it is not easy to reduce or prevent crack cause of impact factor of it. There are so many factors of crack such as material, construction and maintenance environment, and structure, and these are acting in combination. So, this study derives a correlation between the cracks and members through reviewing member crack occurred. And member's attribute, related crack, is analyzed by it. It consider that the basic attribute of member is similar when its requirements are similar. Through this study, therefore, foundation of countermeasure of crack will be provided by prediction of crack shape through member's attribute.

콘크리트 구조물에 발생하는 균열은 구조물의 내력, 내구성, 방수성 등 모든 기능을 저하시키는 주요한 원인으로, 그 대책의 필요성은 구조물이 존재하는 한 계속될 것이다. 하지만 콘크리트 구조물에서의 균열은 재료와 시공 및 사용환경, 구조적 요인 등 다양한 변수가 복합적으로 작용하고 있어 이에 대한 대책 마련과 사전 예방이 쉽지 않은 것이 현실이다. 이에 본 연구에서는 공동주택 외벽에서 균열이 발생한 사례를 분석하여 이에 대한 데이터베이스를 구축하고, 발생한 균열과 부재의 속성간의 관계를 상관관계를 도출하고자 한다. 이는 각 부재가 가지는 기본적 속성이 유사함을 고려하여 균열과 부재의 관계를 분석하고 부재의 속성을 검토하여 균열에 대한 대책 마련에 일조하고자 함이다.
