摘要：

Partial double-layer reticulated shell integrates the advantages of both single layer reticulated shell and double-layer reticulated shell,and it is one kind of space structures used extensively in recent years. But the stability of the lattice shell is not comprehensive. This paper uses software ANSYS to carry out the eigenvalue buckling analyses and the nonlinear analysis of partial double-layer reticulated shell with different value of rise-span ratio and percents of single layer span. Summarizes the relationship between the ultimate bearing capacity of the lattice shell and the percents of single layer well as the rise-span ratios. On the other hand, the effect of geometric imperfection on partial double layer lattice shells will be evaluated. The relationship between the eigenvalue buckling analyses and the nonlinear analysis was also found.
