To master a structure of the ultimate bearing capacity of nonlinear variation, on the structure of the eigenvalue buckling study is necessary. The basic structure of four stages value buckling modes as figure2shows. Eigenvalue buckling modal analysis revealed that orthogonal fasting dome structures' previous order modal in whole buckling buckling primarily, this single net shell structure with local buckling is greatly different from that the integral structure stiffness better; Another from the first order of buckling modal shows that the structure of torsion is very big, surface within the shear rigidity insufficiency.

It is necessary to grasp the ultimate bearing capacity of a structure of the nonlinear variation of the eigenvalues of the buckling of the structure . The basic structure of the first four stages of the value of buckling mode shown in Figure 2. Eigenvalue buckling mode analysis shows that the structure of orthogonal fasting shell buckling mode of the first few bands are dominated by overall buckling, which is the local buckling of reticulated shell structures are very different, indicating that the overall stiffness of the structure than good; other buckling mode from the first-order indicates that the structure of the reverse large surface less than the shear stiffness.
