Abstract

The objective of this study is to develop the plastic greenhouse models which are structurally safe under the weather condition of Seongju and have the dimensions suitable for oriental melon cultivation as well. To grasp the structural features of greenhouses in Seongju, the field survey was conducted on 406 farmhouses which included 2,068 greenhouses. The field survey showed that the roof shape of arch type accounted for the highest rate, but recently even span or peach type became more popular and the width and height of greenhouse tended to increase as the period of use was short. The relationship of the width, ridge height and eaves height were established based on field survey data. Using climate data of Gumi adjacent to Seongju, the regressions were determined for the design wind speed and design snow depth depending on recurrence period. To design the greenhouse models against weather disasters in Seongju, the optimal design loads are 23.7 cm of snow depth and $33.8m{\cdot}s^1$ of wind speed. As the design results, four models of single-span greenhouse, two models of double-span greenhouses including extension were developed.

본 연구는 성주지역에 적합한 참외재배용 내재해형 온실을 개발하기 위하여 참외 재배온실의 구조현황 조사, 최근 기상자료가 반영된 설계하중 산정, 온실모델 설정 및 구조안전성 분석을 수행하였으며 결과를 요약하면 다음과 같다. 성주지역 참외온실의 구조적 특성을 파악하기 위하여 현장 조사한 결과, 온실의 지붕형상은 아치형이 가장 많았으며, 최근에 시공한 온실일수록 복숭아형이 많았으며 폭이 넓어지고 동고도 높아지는 추세였다. 그리고 성주지역에 가장 인접한 구미기상대의 기상자료를 이용하여 재현기간에 따른 설계풍속 및 설계적설심을 산정할 수 있는 계산식을 유도하였으며, 내재해형 온실규격을 만족하는 재현기간 30년의 적설심은 23.7cm, 풍속은 $33.8m{\cdot}s^1$로 계산되었다. 이러한 성주지역의 내재해형 설계기준을 만족하는 참외재배용 단동온실 4종, 2연동온실 및 연결온실을 각각 1종씩 총 6종의 모델을 개발하였다.
