In the seismic area the direct correlation between the strain energy and the axial stress resultants for latticed cylindrical shell structures, has previously been discussed, and an alternative static load modeling associated with the dynamic vibration analytical results has then been proposed. The distribution functions of the previously proposed static seismic load modeling are corresponding to the displacement functions for simple supported shallow shell. In this paper, an alternative static load modeling procedure using the continuum shell analogy has been proposed. The adopted analytical parameters are of the section size of roof members, the horizontal resistance of sub-structure and the total weight of sub-structure. It has been suggested that the present seismic load modeling procedure contributes to the simplicity of seismic design for shell-like space frames.
