Effects of Uplift Resistance on Continuous-Pipe-Foundation of Single-Span Plastic Greenhouse by Steel Plate Pipe Connector

The single-span plastic greenhouses are affected by strong winds which generate uplift resistance causing the bending of members, damage to protective films, and crops. This study performed a field test using static axial tensile load method present basic data prevent greenhouse. Three representative areas were selected, effects pipe connectors, rafter spacing, embedding depth tested. In results, it was found be greatly connector. pull-out at site fixed welding instead connector measured as 4.5 times sliding standard value Rural Development Administration. other sites, measurement below It confirmed that is determined connector, rafters, crossbar pipe. Therefore, seems possible increase continuous foundation through reinforcement results can utilized for commercialization new standards.
