CE75.09 : Structural Health Evaluation and Monitoring of Buildings  2(2-0)
 
Course objectives:

The objective of this course is to provide knowledge in structural health monitoring and evaluation that covers the fundamentals of measuring instrument and technique, structural inspection in steel and reinforced concrete buildings, structural capacity evaluation, and short- term & long-term health monitoring techniques.
 
Learning Outcomes:

The students on the completion of this course would be able to:

  • Conduct structural health inspections in steel and reinforced concrete structures
  • Select the appropriate type of sensors for structural response measurements
  • Conduct load carrying capacity evaluation
  • Monitor and evaluate structural health of long-period structures, g. high-rise buildings and long-span bridges, by ambient vibration measurement

An “A” would be awarded if the student demonstrates thorough knowledge of concepts and techniques together with a high degree of skill and originality in the use of those concepts and techniques. A “B+” would be awarded if the student demonstrates thorough knowledge of concepts and techniques together with a fair degree of skill in the use of those concepts and techniques. A “B” would be awarded if the student demonstrates good level of knowledge of concepts and techniques with considerable skill in using them. A “C+” would be awarded if the student demonstrates that more efforts is required in relation to the required knowledge of concepts and techniques. A “C” would be awarded if the student demonstrates that intensive efforts is needed in relation to the required knowledge of concepts and techniques. A “D” would be awarded if the students’ understanding of the concepts and techniques is unacceptably low.
