Unit Description and General Aims
This unit is concerned with the principles of structural dynamic analysis. It introduces mathematical fundamentals of vibration, the definition of dynamic parameters including mass, stiffness and viscous damping.
The analysis is performed in the time domain by direct integration and in the frequency domain. The analysis is applied to practical structures.
The effect of material and geometric non-linearity on the dynamic behaviour of systems is introduced. Practical cases of failure and success are investigated.
Learning Outcomes
On successful completion of this Unit, students are expected to be able to:
- Make judgements and apply the dynamic equation with viscous damping
Bloom’s Level 5
- Evaluate the modal properties and infer the dynamic behaviour of:
- structural elements;
- multi-degree-of-freedom systems.
Bloom’s Level 5
- Formulate a design of time integration of systems subjected to base excitation and develop response spectra.
Bloom’s Level 6
- Plan modal analysis of systems subjected to base excitation:
- Harmonic excitation;
- Random and earthquake excitation.
Bloom’s Level 6
- Optimise the effect of non-linearity on the natural frequencies of systems.
Bloom’s Level 5
- Determine case studies in relation to dynamic behaviour.
