Development of Large-size Truss Greenhouse with Wind-resistant Features Using Resin Joints

Abstract

In recent years, the intensity of typhoons has increased causing great damage to gardening facilities in not only Okinawa but also the mainland of Japan. For example, typhoon 0314, which recorded a maximum instantaneous wind velocity of 74.1m/s, caused considerable damaged to greenhouses in the Ryukyu Islands. We tried to apply the truss structure to large-scale greenhouses. However, the introduction of such a structure involves very high costs. For implementation in agriculture, it is necessary to reduce the cost of introducing such a structure. In this study, we developed a large-size greenhouse with the truss structure at low cost using resin joints, which are lightweight and inexpensive.
