摘要
Venlo型温室是一种应用广泛的温室结构形式,其常用的跨度为9.6m,间距则不超过5m。当间距增大时,则天沟方向需设置桁架,以取代原有的立柱来承载屋面重量。本文应用结构分析软件ALGOR,对一个12m跨度、8m间距的大空间Venlo型玻璃温室的主框架进行有限元分析,利用分析结果对整个框架进行雪载、风载的强度校核,为大空间Venlo型玻璃温室主框架中立柱和桁架的设计提供参考值。
The Venlo-type greenhouse is a widely used form of greenhouse structure. Its general span is 9.6m spacing, and the space is no more than 5m. When the spaeing increases, it＇s needed to put trusses on the gutter direction, to replace the original column to carry the roof weight. In this paper, the structural analysis software ALGOR is used to process the finite element analysis on the main frame of the Venlo-type glass greenhouse. Then the analyzing result is used to do the strength check of snow load and wind load on the main frame, which is to provide the reference value on the designing of the pillars and trusses in the main frame of the Venlo-type glass greenhouse.
