摘要
影响板锥球面网壳结构稳定承载力性能的因素很多,其中主要有结构形式、矢跨比、板件材料等。首先介绍了板锥球面网壳的形式和分类,接着提出特征值屈曲分析和弧长法相结合是进行结构非线性屈曲分析的一种有效方法,通过算例,分析这三个影响因素对稳定承载力性能的影响程度,并得到一系列重要的结论。
There are many influence factors on the stability capacity behavior of plate-cone spherical reticulated shell,lincluding structural forms,rise-to-span ratio and plate material which are three main factors among all.Structural forms and classification of plate-cone spherical reticulated shell are introducied first,then put forward an effective method that combining eigen-buckling analysis and arc-length method for nonlinear buckling analysis,through calculation example,influencing degree of stability capacity behavior by the three factors is analysed,then generalizes a series of important conclusions are got at last.
