摘　　要：建立1个主架和4个次架相间排列的三连拱温室受风、雪荷载时的计算模型，阐述了它的计算方法；同时对规范中没有说明的附加风压力、附加风吸力、风载高度变化因数和多连拱型屋面的风载体型因数作了分析。根据计算结果提出了改进温室结构设计的建议。The structure calculation model of a tri-arch greenhouse under wind and snow load is developed. The additional wind pressure,the additional suction and the height changing factor of wind load as well as the shape factor of wind 1oad for multiarch roof coverings,which are not yet mentioned in the current constructional standards,are analyzed. Based on the calculation results,some suggestions for the improvment of the greenhouse structure design are provided.
