| Abstract: | In light of the geometrical large deformation and small strain of the air-supported structure and on the basis of the non-linear finite element iteration method,different loading conditions including snow load and wind load are simplified,the membrane stress and the largest displacement of the chosen membrane with certain interior pressure are analyzed,and the load-deformation relations of the structure are obtained.The relevant calculation formulas are also given.The results of analysis by using the ANSYS software with the triangle finite element are compared with those by using the simplified calculation method,which turns out to be very close.It is thought that the presented simplification method based on the non-linear finite element iteration method is right and feasible. |
