Abstract: This project is a complex space steel roof structure. The structure model of the steel roof was selected. The linear overall stability analysis and the large displacement geometric nonlinearity overall stability of the roof structure were performed. The stability of the bearing capacity under different load combinations and different analytical conditions was compared.
Keywords: roof stability; linear overall stability analysis; defect structure; geometric nonlinearity
