Abstract
The stability of arch structure and shell structure is an important part of structural analysis,which is the key to determine the bearing capacity of the structure.For this new type of arch-reticulated shell hybrid steel structures,there is no uniform design specification and stability studies are limited to engineering examples.In this paper,based on the arch-reticulated shell hybrid steel structures of a gymnasium in Hebei,combined with the present research of this kind of structure stability,using the finite element software MIDAS/GEN and ABAQUS,eigenvalue buckling analysis of structures and single arch,arch group and the whole structures elastoplastic analysis were conducted.At the same time,effects of initial geometric imperfection and asymmetric loads on the bearing capacity of the structure were investigated.关键词
