| Abstract | The calculation of thin-walled structures undergoing large deflections, especially due to applying dynamic loads, is a complex procedure. Structural designers always need help in understanding the behavior of these types of structures. The help may come from the numerical simulation, which are often developed using the finite element method. This thesis is to present the theoretical background and implementation of the geometric nonlinear dynamic analysis of thin-walled frame structures. Firstly, the linear and nonlinear behaviors of thin-walled structures are studied. Prismatic beams of arbitrary thinwalled cross section and conservative type of loading are considered. The algorithms for the automatic incremental solution of nonlinear finite element equations in static analysis are studied. Next, the solution methods for dynamic analyses using implicit time integration are implemented into the general-purpose finite element program called XFINAS. A large variety of selected sample analyses are described to verify the correctness of programming and algorithm, the reliability of the beam element, and to show some of the cmTent solution capabilities of the program. |
