지붕곡률에 따른 복숭아형 온실의 풍압계수 평가

Abstract

Since the early 1990s, the massive protected horticulture in Korea has become modernized corporatized. Korea currently has the second largest the total cultivation in all over the world parallel to Japan and Spain, following China. Accordingly, safe and efficient design of the horticultural facilities draws a great deal of attention. For instance, a greenhouse is one of the most widely used facilities for vegetables or flower. The greenhouse is regarded as a light structure, which is vulnerable to wind load, since the design of the structure is carried out using a smaller safety factor than one of general building structures. As occurrence of large-scale typhoon, whose maximum wind speed is 40 – 60m/s, and strong wind have been frequent in Korea recently, damage on agriculture facilities increases accordingly. Therefore, a new design code for greenhouses based on Korean environment data is required. In this study, roof curvature wind pressure coefficients and local pressure coefficient of peach-type were investigated and proposed using wind tunnel testing for the new design code of Korean greenhouses.
