| Abstract: | Nonlinear finite element analysis was carried out in shape formation of a post-tentioned and formed hyperbolic paraboloid latticed shell model.Considering both geometry and material nonlinearity,new FEM refering tube to tube contact based on beam and truss elements,was employed.Connector elements were used to simulate the bolt connection of the top joint,and the end of web.The result showed that new method was relatively much more accurate than the previous ways for the shaped size,and the theoretical value... |
