초록

연동비닐하우스의 기초는 주로 수직하중을 고려하여 소형의 얕은 콘크리트 기초로 설계 시공된다. 그러나 최근 강풍과 같은 이상기후로 인하여 기초에 설계 강도 이상의 수평하중 및 인발하중이 작용하여 온실기초의 안전성 문제를 야기하고 있다. 비닐하우스 기초의 안전성을 합리적으로 평가하기 위해 지반-기초의 상호작용에 의해 발현되는 회전 및 인발강성을 평가하여야 하며 이는 상부 구조재의 안전성에도 영향을 미치는 요소가 된다. 본 연구에서는 내재해형 연동비닐하우스 규격 기초를 형상에 따라 분류하여 3개의 대표 기초 유형을 선정하고, 기초 유형별 수평하중 가력실험 및 이론 해석을 수행하였다. 실험 및 해석의 비교 분석 결과, 기초-지반 접촉면의 성질과 지반의 역학적 성질이 동일할 경우 기초는 지반과의 접촉면적비에 따라 회전저항성능에 차이를 보이는 것으로 나타났다.

The foundation of the multi-span greenhouse structures is designed with small shallow concrete foundation considering mainly the vertical load. However, recently, due to an abnormal climate such as strong wind, horizontal load and up-lift load over design strength are applied to the foundation, causing safety problems of the greenhouse foundation. In order to reasonably evaluate the safety of greenhouse foundations, rotational and pullout stiffness expressed by the ground-foundation interaction should be evaluated, which also affects the safety of the upper structural members. In this study, three representative basic foundation types were selected by classifying greenhouse standards in Korea according to the shape, and the horizontal loading tests and theoretical calculation were performed for each foundation type. As a result of the comparison and analysis of the test and calculation, it was found that rotational resistance of the foundation is different according to the ratio of the contact area between the foundation and ground when the conditions of the foundation - ground contact surface and the mechanical properties of the ground are the same.
