Dynamics of Structures (a.a. 2019/20)

Programma

Objective:

This course serves as a prelude to other courses in the Civil/Structural Engineering curriculum that deal with more advanced courses in structural dynamics, earthquake resistant design and analysis.  It is considered as the pre-requisite course for subsequent courses in earthquake engineering, but has a different, introductory, emphasis.

 

Course Conduct and Evaluation:

• Nonlin, USEE, MathCAD or similar tool will be used as the general medium for preparing the assignments and implementing the analysis algorithms.
• Homework assignments will be accepted up to 4 days beyond the deadline for submission at a penalty of 20% per day.
  The instructor will post supplementary course material on the website
• Improper collaboration will not be tolerated, and no debate will occur concerning this point.
• Latest information regarding the course can be found at the web site
• Computer-based homework assignments can be e mailed to

Bibliografia

• Clough, R.W., and J. Penzien,  Dynamics of Structures, Second Ed., 1993, McGraw Hill. (The first edition of this seminal book is also quite adequate, though like the second edition, it uses US Customary Units, which can be vexing.)
• Chopra, A.K., Dynamics of Structures  (Theory and Applications to Earthquake Engineering), Fifth Ed., 2015, Prentice Hall. (The first four editions of this book are also quite adequate for this course.)

Esame

The lectures will be given at times announced by the Program Coordinator’s office. There may be additional problem solving tutorials taught by the staff. There will be one term test and a final examination. Tentatively, the term test will have a weight of 30%, the three assignments will have a total weight of 30%, and the final exam will have a weight of 40%
