- W2984396677 abstract "Due to the more and more prominent nonlinear buckling problems of large-span arch structures in engineering applications, and the lack of special design methods of large-span arch structures in existing specifications, this paper establishes a simplified mechanical model for the stability of arch structures with initial geometric defects. The finite element model of arch structure is established by using finite element software, and the characteristic value buckling analysis and geometric nonlinear analysis are carried out to find out the buckling mode of arch structure, and the sensitivity of defects to arch structure is studied. The results show that the existence of defects will reduce the bearing capacity of the structure, and the increase of defects will change the deformation form of the structure." @default.
