3개동 아치형 하우스 단지의 위치별 풍압계수 분포 연구

The study on wind load that greatly affects the structure design of agricultural facilities has been conducted mostly in regards to independent a single-span arched house or two-span arched house. However, looking at the actual greenhouse layout, they are installed in a single-span arched house or two-span arched house of several complexes rather than a single complex. Like this, the changes in the position of greenhouses can affect the distribution of wind pressure coefficients, and therefore it needs to closely examine the changes in wind pressure coefficients depending on the position of greenhouses. Accordingly, the study builds a single-span arched greenhouse with a constant distance between complexes, calculate wind pressure coefficients generated from each surface of a greenhouse through the wind tunnel experiment under the conditions of boundary layer flow, and analyze changes in wind pressure coefficients from the surface of a single-span greenhouse by each position according to wind direction in order to provide the basic data necessary in structure design of greenhouses.
