Due to a heavy snowfall in winter and also a strong wind as a typhoon sometimes stroke, there have been strong needs to develop anti-disaster single-span greenhouses. The first theme was carried out to provide basic insights on factors affecting structural stabilities of 8.2∼10m-wide single-span greenhouses with the high eaves, which greenhouses have been installed to easily utilize agricultural machines and reduce hot temperature damages, and to ultimately present structural stabilities for developing standardized single-span greenhouses by way of structural analysis and snow-load test. The general eaves' height of single-span greenhouses to utilize agricultural machines was surveyed to be within the range of 2.0~2.6m in general. Therefore, structural stabilities for 8.2∼10m-wide single-span greenhouses with the eaves’ height above 2.0m were presented for three types of the structure such as a basic, a struts-installed and a truss structure. The snow-load test was conducted for the verification of structural analyses. The experiments showed that FEA predictions seemed to be credible although there was a slight discrepancy between the predictions and experimental measurements.
The second theme was conducted to develop standardized anti-disaster models of single-span greenhouses with heat insulating materials widely used in southern regions to save the heating energy, enhance the land use efficiency. The results of the survey made in Milyang and Jinju showed that the greenhouses were classified as the arched and the shape of a three-quarter which had various widths of 12∼28m and heights of 3∼4m. As for pipe frames, it had rafters of φ31.8×1.5t@600 and columns of φ48.1×2.1t@3,000. Most of heat insulating material was a mixture of ‘non-woven fabric 80g+bifold heat-insulating materials+cotton 15oz+non-woven fabric 80g’ though kinds of the materials were diverse according to farmer’s demand.
Structural stabilities of the greenhouses with heat insulating materials were analyzed for various specifications of the pipe and the widths of greenhouses. Finally, the load test for single-span greenhouses showed that the FEA calculations seemed to be also credible.
