CE75.02 : Structural Dynamics for Tall Buildings  3(3-0)
 
Course objectives:
As modern structures are becoming slender and light, they are also becoming more susceptible to dynamic loadings. Various examples of real-life dynamic problems that frequently confront civil engineers include: aerodynamic stability of long-span bridges, earthquake response of multi-story buildings, impact of moving vehicles on highway structures, etc. The traditional engineering solutions to these problems, based on "static force" and "static response", are no longer valid in most cases. Many of these problems have to be tackled by applying knowledge of structural dynamics. Thus, a basic understanding of the dynamic behavior of structures as well as the underlying principles is essential for structural engineers
 
Learning Outcomes:

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

  • Gain basic understanding of principles of structural dynamics
  • Integrate the principles of structural dynamics in structural design of tall buildings and earthquake engineering
  • Analyze and solve problems in dynamic response and behavior of tall buildings

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.
