초록

시스템 동바리는 건설공사 및 토목공사 현장에서 수직하중을 지지하기 위해 임시로 설치되는 가시설물로, 재사용되는 개별 가설기자재를 조립하여 설치된다는 특징이 있다. 이러한 특징은 설치가 완료된 시스템 동바리의 성능저하로 연결될 가능성이 있으며, 실제로 일정 규모 이상의 시스템 동바리를 설치할 경우 설계단계에서 구조적인 안전성을 점검받도록 제도적으로 규정하고 있음에도 시스템 동바리의 붕괴로 인한 사고가 지속적으로 발생하고 있다. 이에 따라 다양한 제도적 방법을 통해 시스템 동바리에 대한 안전관리를 시행하고 있으나 현재 제도에서는 개별 가설기자재의 재사용에 따른 가시설물의 성능저하를 고려하지 않는 실정이다. 따라서 본 연구의 목적은 시스템 동바리의 조립에 사용되는 자재를 신재와 재사용 자재로 구분하여, 정의된 모델로 각각 조립했을 때의 압축성능을 종합적으로 평가하고 그 성능의 차이를 비교·분석함으로써 시스템 동바리의 구조설계 및 구조검토 시 그 결과를 고려할 수 있도록 하는 정량적 기초 데이터를 제시하는 것이다. 본 연구의 결과는 기존 가시설물의 성능을 대상으로 하는 안전제도 및 기준에 대한 정량적인 평가가 가능하며 추후 가시설물의 안전관리 제도 개선을 위한 방향성을 제시할 수 있는 연구사례로써 그 의미가 있을 것으로 기대된다.

System support is a facility that is temporarily installed to support vertical loads at construction sites, and is assembled and installed by reused individual members. These characteristics are likely to lead to poor performance of installed system supports, and even though it is institutionalized to check structural safety at the their design phase, accidents continue to occur at the construction site. Accordingly, safety management of system support is implemented through various institutional methods, but the current system does not consider the performance degradation of temporary facilities due to the reuse of individual temporary members. Therefore, the purpose of this study is to verify the performance of assembled system support. In order to do achieve this purpose, the authors divided individual system supports into unused and used groups and performed compression performance test with defined models assembled with those two groups of system supports. The results of this study are expected to be meaningful as a research case that can quantitatively evaluate safety systems and standards for the performance of existing temporary facilities and suggest directions for improving the safety management system of temporary facilities in the future.
