CE72.22 : Wind and Earthquake Engineering  3(3-0)
 
Course objectives:
Wind and earthquake excitations are two major dynamic loadings for many modern civil engineering structures. Therefore, civil engineers need to learn more about these loadings and their complex nature.  The objective of this course is to provide an in-depth understanding of these loadings and their effects on buildings and structures. This will enable engineers to ensure the safety and serviceability of structures under such loadings.
 
Learning Outcomes:
On successfully completing this course, students will be able to:
  • Identify the characteristics of two major dynamic loadings on modern civil engineering structures and the structural responses to these dynamic loadings,
  • Apply the theory of structural dynamics to assess structural response under wind and earthquake loadings,
  • Design buildings and structures for effective wind and earthquake resistance.
