Statik und Dynamik 2 (Statics and dynamics 2)

Computerorientierte Statik und Dynamik (Computer oriented statics and dynamics)

Topic

Theoretical backgrounds as well as the application of numerical methods in structural analysis are in the focus. With the VV/DV, the stiffness of a structure as well as its action is mapped into a linear system of equations and demonstrated as the basis of numerical methods in structural analysis. The necessary extension of numerics up to commercial software application is treated in more detail on the basis of the equilibrium on the deformed system. Important guidelines for handling structural analysis programs are derived from this, which prepares for requirements in practice. This includes dealing with time-dependent loading, which causes the structure to vibrate. With the help of modal analysis, statements can be made in most applications about the dynamics of the supporting structures as well as about necessary measures. However, the approximate nature and limitations of linear vibration theory are also discussed on the basis of nonlinear influences.
