| Abstract: | Based on the geometrically and material non linear behaviour of the composite barrel vaults in buckling, the stability behaviours are analyzed by FEM under T. L. coordinate. The effect of plastics is studied by the plastic node method to simplify calculation. The factors of main imperfections are involved. The results of the examples and experiment are compared with the theoretical results to study the validity of the theory and the buckling characteristics of the structure. |
