기초형식 및 지반조건에 따른 하우스파이프기초의 인발저항력 특성

Abstract

The area of facility horticulture in Korea is increasing rapidly, the single-span pipe house which uses galvanized steel pipe as the main rafters occupies78.7% of the facility area. Lightweight structures such as the single-span pipe house are vulnerable to meteorological disasters such as strong winds,economic losses of the state, local governments and farmers are continuing as construction does not meet the design standards. In order to minimizeeconomic losses in the horticultural specialty facilities sector, the Rural Development Administration has been operating the horticultural disaster resilientstandard for horticultural specialty facilities since April 2007. The only standard for the pipe connector is the disaster resilient standard, there is nostandard for the uplift capacity of the house pipe foundation and the research on it is also insufficient. The purpose of this study is to investigate thecharacteristics of uplift capacity according to the foundation type, compaction ratio and embedded depth through soil box test. The results of themaximum uplift capacity according to the type, compaction ratio and embedded depth can be used as the basic data for the basic design of the pipehouse conforming to the disaster resilient standard. Due to the limitation of soil box test, it may be different from the behavior of pipe house installedon site. In the future, the field test and the actual pipe house should be made and supplemented by comparing this result with the field test values.
