Abstract
The procedure for the analysis of a load-bearing structure will be introduced in this chapter. Structures will be considered, which consist of multiple elements and are connected with each other on coupling points. The structure is supported properly and subjected with loads. Unknown are the deformations of the structure and the reaction forces at the supports. Furthermore, the internal reactions of the single element are of interest. The stiffness relation of the single elements are already known from the previous chapters. A global stiffness relation forms on the basis of these single stiffness relations. From a mathematical point of view the evaluation of the global stiffness relation equals the solving of a linear system of equations. As examples plane and general three-dimensional structures of bars and beams will be introduced.
