Double Non-Linear Mechanical Characteristics of Transmission Tower Structure Based on Model Amendment
Transmission tower, being of evident nonlinear characteristic, is a complex space structure. Linear theory is generally adopted in the process of designing, which results in a waste of resource and disaster. Starting from the problems exiting in the process of transmission tower designing, the space beam element is adopted in the thesis, which reduces material nonlinearity through the rod end of the plastic method, and the geometric large deformation problem is involved by considering the amendment of the element stiffness matrix. Arc-length method of iterative computation is adopted as the solution method. On the premise of clarifying the process of dual non-linear solution, this thesis combines specific project example through self-organizing the finite element programming to calculate displacement - load curve, and the results show that the transmission tower structural system possesses obvious nonlinear characteristics. The research lays a foundation for improving the accuracy of space truss structure and developing the large specific finite element software.
