摘要
施威德勒椭球形弦支穹顶是弦支穹顶结构的一种新型结构形式,利用有限元计算软件ANSYS对椭球形弦支穹顶和单层网壳进行特征值屈曲分析。通过对不同矢跨比的对比分析,预测施威德勒椭球形弦支穹顶的屈曲特性。
Schwedler elliptic suspendome is new patter structure shape of suspendome.the finite element software ANSYS was used to do characteristic value buckling analysis for schwedler elliptic suspendome and single layer reticulate.Analysis to suspend-dome and single layer reticulate is conducted separately to the five type suspendomes which have the same span but different rise-span,every performance of suspendome was expatiated in the paper.Through the comparation between supsendome and single layer reticulate,the buckling of schwedler elliptic suspend-dome was doped out.
