摘要：为了确定柱面空腹网壳结构从稳定平衡状态变为不稳定平衡状态的临界荷载和屈曲后的形态,深入研究柱面空腹网壳结构的稳定性。采用有限元分析方法,在对柱面空腹网壳结构进行计算分析的基础上,进一步进行屈曲模态分析及非线性参数化屈曲分析。目前方钢管构成的空腹网壳在已有研究中并不多见,以方钢管构成的空腹网壳结构为主要研究对象,分析该类结构矢跨比、结构厚度、截面尺寸等参数变化对结构极限承载力的影响,从而得出在不同参数变化下柱面空腹网壳结构的稳定性情况。
In order to determine the critical load and the buckling mode of a cylindrical vierendeel shell latticed changed from stable equilibrium state to unstable equilibrium state,the stability of cylindrical vierendeel shell was studied deeply.Based on the finite element analysis of the cylindrical vierendeel latticed shell,the buckling mode and nonlinear parametric buckling analysis were further carried out. Currently,there are far researches on the cylindrical vierendeel latticed shell composed of square steel tubes. Therefore,the paper took the cylindrical vierendeel latticed shell composed of square steel tubes as the main object of research. The effects of different parameters such as span ratio,structure thickness and section size on the ultimate bearing capacity were analyzed. Thus,the structure＇s stability under different parameters was obtained.
