Plate-cone reticulated shell is a new type of space structures with good mechanical behavior and technical economy. In this paper, a continuum analogy method for plate-cone reticulated shell which is equated to the three-layer thin shell is put forward. Based on mechanical characteristics of plate-cone reticulated shell, the equivalent stiffness is derived through the theory of elasticity. Then, the plate-cone reticulated shell is equated to a special type of three-layer thin shell working interactively, the governing differential equations are derived on the basis of the theory of thin shells, these differential equations being from the displacement method and the mixed method of derivation. The solution of this system of differential equations gives the displacements and internal forces of plate-cone reticulated shell.
