Learning Outcomes
By the end of the course, the student must be able to:
- Develop insights into the working of struture dynamics from first principles
- Assess / Evaluate the dynamic response of structures under vibrations of various types
- Conduct response spectrum analysis
- Conduct numerical analyses of single and muti-degree of freedom systems
- Conduct hands on vibration-based analysis to infer the dynamic properties of structural systems
Transversal skills
- Continue to work through difficulties or initial failure to find optimal solutions.
- Use a work methodology appropriate to the task.
- Plan and carry out activities in a way which makes optimal use of available time and other resources.
- Communicate effectively, being understood, including across different languages and cultures.
