| Abstract: | This paper uses the geometrically nonlinear finite element theory to investigate comprehensively the stability behavior for the partial double layer ribbed lattice spherical domes, including the critical load and buckling behavior variations with respect to the structural parameter changes (rise span ratio, truss height), various analytical models and different boundary conditions. Many important practical conclusions have been obtained from a series of numerical results. |
