Aim: Design af beam and frame structures is in practice made by extensive use of computer programs. Non-linear phenomenae have an increasing importance as the structures tend to get more slender and the designer utilizes the structure more efficiently. The aim of the course is to enable the students to develop computer methods and use existing software for analysis of beam and frame structures. The course will enable the students to
a) develop programs for analysis and design of cross-sections or joints with a linear or nonlinear material model.
b) develop facilities to a finite element program for beam and frame structures that allows non-linear analysis such as large displacements, stability and dynamics.
c) gain insight into methods of analysis for thin-walled beams based on Vlasov beam theory.
d) use existing software packages and have an insight into the fundamental problems in coupling of programs for analysis and design with CAD-systems. |
