Suggested readings:

  • Dynamics of Structures: Theory and applications to earthquake engineering. By A. Chopra, 3rd Edition, Prentice Hall.
  • Eurocode 8 (CEN-Brussels)
  • Handout notes by the instructor
  • Various published articles

Notes:

Prerequisites

  • Design of reinforced concrete linear elements.
  • Design of steel structural components.
  • Design of steel structures.
  • Design of reinforced concrete structures.
  • Structural dynamics.

Teaching and learning methods

Lectures accompanied by a series of about 5-6 homework assignments plus a term project, typically involving the dynamic earthquake analysis of a small building using commercial software such as ETABS, SAP, etc. 2 graduate students and the instructor are also available for answering questions.

Assessment and grading methods

A 3-hour final written exam. Successful completion and submission of all homework assignments and of the term project may count up to 2/10 for the final grade.
