Elastic & Plastic Calculation of Frame Structure of Gutter-Connected Greenhouse

According to the mechanics theory and constructional standards, the half structure calculation model of a gutter connected greenhouse under wind load and snow load was developed. And loading combination was considered. After elastic & plastic calculation of frame structure, its one and two phase stress and stability coefficient of frame column as well as stability coefficient of frame were obtained with the finite element method and with constructional standards. Its structure was improved in terms of the danger zone of frame obtained by calculation. The result indicates that the structure of the improved greenhouse is rational, and has fine mechanical properties.
