풍동 실험을 통한 개방형 비가림 농업시설의 풍압계수 산정 및 특성 분석 = Wind Pressure Coefficients of Open-Type Rain-Shelter Structures from Wind-Tunnel Experiments

다국어 초록 (Multilingual Abstract)

Ensuring the structural safety of agricultural facilities is increasingly important as extreme weather events intensify under climate change. This studyestimates wind pressure coefficients for open-type rain-shelter structures in Korea through wind-tunnel tests and analyzes their distributions to supportdesign. Tests on single- and multi-span models evaluated roof-section responses and guided the proposal of design coefficients. Under 0° (frontal) wind,pressure peaked at the windward eaves; under 90° (crosswind), the strongest contrasts appeared near the span center with recurrent local fluctuationsat the side edges. Grouping pressure-tap data by roof section and averaging them yielded representative coefficients that capture these recurring patterns.
Treating structural type and wind direction as independent factors produced coefficients more suitable for practical design and risk reduction. Futurework will extend the scope of structures and wind conditions to provide a broader basis for standardizing wind-resistant design guidelines for open-typeagricultural facilities.
