The distribution functions of the previously proposed static seismic loading associated with the dynamic vibration analytical results are corresponding to the displacement functions for simple supported shallow shell. In this paper, an equivalent lumped mass system and a static loading model for longitudinal, circumferential and vertical direction have been proposed using the continuum shell analogy. The adopted shell-like space frame is single layer latticed cylindrical shell structure having sub-structure which consists of steel tubes. 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 shown that the estimated response axial forces by the present seismic loading are in good agreement with the maximum response axial forces by the dynamic analysis. It has been suggested that the present seismic load modeling procedure contributes to the simplicity of seismic design and evaluation of seismic capacity for shell-like space frames.
