These tutorials are for use by my students and may be instructive for others who need a refresher in structural dynamics. 

They are a review of the material taught in typical structural dynamics classes (CE212) and can be allow students to understand the basics of structural behavior before we delve into the design problems.

Most of the work here is closely tied to the structural dynamics textbook written by Anil Chopra.  I strongly suggest that you use this textbook to gain a full understanding of a very complex subject.  See the references listed below.
