| Abstract: | 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. |

| Keywords: | Schwedler elliptic suspendome characteristic value buckling rise-span |
