Abstract
본 연구에서는 수소 충전소와 같은 폭발 가능성을 가진 구조물들의 안전 설계 방안으로 방호패널이 희생 부재로 설치되어 구조물의 직접적인 피해를 최소화하고 회복 탄력성을 가질 수 있어야 한다고 제시하였다. 이를 위해 비상체의 고속 충돌상황에서 방호 패널이 구조물과 밀착 또는 이격 설치되었을 때 구조물이 받는 영향을 정량적으로 평가하는데 실험의 초점을맞추고 있다. 실험 설계는 우수한 재현성을 위해 기존에 주로 사용한 콘크리트 구조부재 대신 강판을 사용하며, 철판 배면의변형 차이를 통해 구조부재의 충격을 비교 ․ 분석하였다. 또한, 방호 부재의 이격재로 사용한 탄성체의 물성 변화와 방호부재및 탄성체에 따른 충격파 전달 시간의 차이가 구조부재에 미치는 영향을 조사하였다.
This study suggested that protective panels should be installed as sacrificial members as a safetydesign method for structures with potential explosions such as hydrogen charging stations tominimize direct damage to the structure and have resilience. To this end, the focus of the experimentis on quantitatively evaluating the impact of the structure when the protection panel is installed closelyor spaced apart from the structure in a high-speed collision situation of the projectile. The experimentaldesign used steel plates instead of concrete structural members mainly used in the past for excellentreproducibility, and the impact of structural members was compared and analyzed through deformationdifferences on the back of the steel plate. In addition, the impact of changes in the physical propertiesof the elastic body used as a separation material for the protective member and the difference in shockwave transmission time according to the protective member and the elastic body on the structuralmember was investigated.
