摘  要:
借助于有限元通用程序,对简化平面模型与部分空间模型的作用进行了对比分析。结果表明:在对连栋塑料温室进行结构分析时,一般情况下可用简化平面计算模型代替部分空间作用的计算模型,以简化求解问题的工作量和难度。但在非均匀雪荷载作用下,用简化平面计算模型代替部分空间作用的计算模型,要注意空间作用对主拱承载能力的不利影响;对于需要精确分析和优化设计时,最好采用部分空间作用的计算模型。

摘  要:
Depended on ALGOR finite element analysis system, the contrast analysis of the element carrying capacity was discussed for East-China type multi-span plastic greenhouse under the plane calculation model and the space calculation model. The results indicate: Generally speaking, it is feasible in using the plane calculation model instead of the space calculation model for structural analysis of multi-span plastic greenhouse in order to simplify calculation workload and difficulty but we must pay attention to that space effect has disadvantageous influence upon the main-arch carrying capacity under the uneven snow loading. We had better choose the space calculation model for those which demand precision analysis and optimization designs.
