    12. Discussion
Knowledge and Understanding
  • For a passing grade the doctoral student must
  • 1. Understand and evaluate the stability phenomenon and understand the fundamental difference between the critical load and design load
    2. Understand the different types of stability phenomena, flexural, torsional buckling and flexural-torsional buckling
    3. Understand the difference between I, II and III-order analyses
    4. Understand and use different methods to calculate the critical load
    5. Understand the background to the buckling of frames and bows
Competences and Skills
  • For a passing grade the doctoral student must
  • 1. Be able to calculate both critical load and design load
    2. Be able to identify different types of stability phenomena, flexural, torsional buckling and flexural-torsional buckling
    3. Be able to calculate the critical load for simple structures according to I, II and III order analysis
    4. Be able to calculate the buckling load of frames and arches
Judgement and Approach
  • For a passing grade the doctoral student must
  • 1. Be aware of the critical load is a vital parameter to determine the load bearing capacity of a structure
    2. Be able to apply both exact and approximate methods for estimating the critical load of various types of structures.
