Abstract:Museum of Geological Sites in Zigong Dinosaur Museum is a structure in the mountainous region. Reinforced concrete frame structure was adopted in the lower structure, and single layer elliptical shell was adopted in the upper structure. Single layer elliptical shell of the upper structure was analyzed by using finite element method. Some properties were discussed as well. Several conclusions were drawn and suggestions were presented for similar engineerings.
Keywords:steel structure; single layer elliptical shell; finite element method; buckling analysis
