제주형 작물재배용 비닐하우스의 모델개발 : 풍하중에 대한 수치해석 = A Development of Cheju-style Plastic Greenhouse Model for Crop Growing -Numerical Analysis for Wind Loading-

다국어 초록 (Multilingual Abstract)

An elastic analysis under wind load is performed for the double layered plastic greenhouse model developed particularly for minimizing damages under typhoons at Cheju Citrus Research Institute in Chejudo. General EVA frlm is used for the inner covering and for the outer covering the developed special film whch would break the wind pressure down is used. Based on the wind tunnel test. this special film will reduce effectively the wind speed by up to 86 to 98% under very controlled situation. Many more tests need to be performed to adopt the results to greenhouse analysis.
Based on the elastic analysis performed in the study, the behavior of the greenhouse is changed dramatically due to the boundary conditions. Not like other researchers before we applied dead load of the concrete support at the ground pipe and fixed support boundary conditions at the 4 corner pipes. The analysis shows that the greenhouse is lifted and pulled the pipe out of the ground due to the sucking wind pressure. The behavior of the greenhouse is very much similar to that one real greenhouse failure. Therefore, not only we need to find the realistic boundary conditions for the supports, but also need to perform many more researches to find how to rest the pipe supports on the ground without losing economy.
