【Abstract】 Tension compensation method and the inverse iteration method are used to determine the initial shape of suspend domes.The effectiveness of these methods is verified through some data of the practical engineering.In this paper,two methods of the morphological analysis that consider the influence of the upper structure or not are compared.Then the influence of the own weight on analysis results is investigated.更多还原
