| Aim: Structural dynamics is about determination of deflections or action effects in structures with external loadings or motions of the foundations varying so fast in time that accelerations of the structure introduce a high level of action effects, so that a statical calculation is insufficient. The aim of the course is to give a fundamental introduction into the theories and in particular to the study of vibrations of beams and frames. |
| Contents: Single degree of freedom systems. Free and forced vibrations. Amplification, resonance. General properties of linear systems. Methods for determination of natural frequencies, in particular the lower ones. Modelling of structures as multi degree of freedom systems. Formulation of the basic equations as matrix equations. Forced vibrations, resonance and antiresonance. Calculation technique for minor systems. Computer methods for larger systems. Vibrations of continuous structures with special emphasis on beams and frames. Exact methods and approximate methods. Influence of viscous damping on structures of one or more degrees of freedom. |
