Course content

The following is covered: The single-degree-of-freedom system. Response of dynamic loads by superposition in time and frequency domain. Time domain integration. Continuous systems (partial differential equations), generalised single-degree-of-freedom systems, dynamic respons by modal superposition. Damping mechanisms and models. The equation of motion in a matrix format. Numeric solution to the problem of free oscillations. Direct solution of the equation of motion in time and frequency domain. Response calculations for relevant load cases (e.g. wind and earthquake).

Learning outcome

The course is intended to provide necessary knowledge for the determination of structural response from dynamic loads, and experience in the modelling and calculation of dynamic response for simple structural systems.

Learning methods and activities

Lectures and model illustrations. Numerical and computer exercises. Laboratory projects and demonstrations of dynamic response of simple structural models. The course will be given in English if necessary. At the re-sit exam the examination form may be written or oral.

Compulsory assignments

Recommended previous knowledge

The course assumes basic knowledge of the finite element method for beams and frames, mass point dynamics and Fourier-analysis.
