Study on Anti-collapse Behavior of Solar Greenhouses Covering Rigid Plate under Snowstorm

Abstract : To analyze the effect of stressed skin action of rigid plate covering on anti-collapse behavior of solar greenhouses under snow load, the numerical simulation on the overall collapse process of single skeleton structure and 6-skeleton overall spatial structure with rigid plate covering were conducted on ANSYS. The collapse modes of solar greenhouses and snow load-displacement curves were obtained. The effects of different parameters on the anti-collapse behavior of solar greenhouses under snow load were also analyzed. The results showed that the stressed skin action of the covering could provide lateral support for the skeleton and increase integral rigidity of the structure and the bearing capacity to resist snowstorm. The lateral support of 8mm thick PC sun board equals that of 4 purlins, 10mm thick PC sun board equals 6 purlins, and 12mm thick PC sun board equals 8 purlins. It is suggested that skeleton interval is about 1m.
