Learning OutcomesBy the end of the course, the student must be able to:
- Develop insights into the working of structural analysis and stability from first principles
- Assess / Evaluate the stability of structural components, frames under various types of loading
- Model nonlinear geometric effects in basic structural components and frame structures
- 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.
