Abstract

Damage caused by meteorological disasters in domestic greenhouses is increasing. Since 2007, Ministry of Agriculture, Food and Rural Affairs, and Rural Development Administration have been offering the design standards and specifications for disaster-resistant greenhouse. In a single-type greenhouse specifications, continuous pipe foundations are used to increase the uplift capacity. However, there is no content on the evaluation method of the ultimate uplift capacity. In this study, the uplift capacity characteristic according to the shape of the continuous pipe foundation was analyzed for the prediction of the ultimate uplift capacity. The ultimate uplift capacity was measured through laboratory model test. The ultimate uplift capacity was analyzed by installing continuous pipe foundations with different relative density, continuous pipe diameter, rafter spacing, and unit of rafters. A theoretical equation for the ultimate uplift capacity of continuous pipe foundation was proposed, considering existing theoretical equations for strip footings, pipelines, and piles. The uplift capacity calculated using estimation equation was compared with experimental values for verification, showed the highest correlation with the model test results, and produced the smallest error. Allowable ultimate uplift capacity of continuous pipe foundation can be estimated by taking into account an appropriate safety factor.
