Abstract
As the progress of society and development of cities, the demand for super large span dome gradually appears. Based on an architectural conception proposal, this paper presents the preliminary research on the structures of 800m diameter super large span dome. The feasibility of several types of structures is analyzed, including double-layer reticulated shell, mega reticulated structure, suspen-dome and cable dome. The preliminary results show that suspen-dome costs too much material, cable dome needs high prestress and tremendous boundary supports, mega reticulated structure causes concentrated reactions and the double-layer reticulated shell fits the 800m diameter dome best.
