Often times, people ask some simple questions regarding modal analysis and how structures vibrate. Most times, it is impossible to describe this simply and some of the basic underlying theory needs to be addressed in order to fully explain some of these concepts. However, many times the theory is just a little too much to handle and some of the concepts can be described without a rigorous mathematical treatment. This article will attempt to explain some concepts about how structures vibrate and the use of some of the tools to solve structural dynamic problems. The intent of this article is to simply identify how structures vibrate from a nonmathematical perspective. With this being said, let's start with the first question that is usually asked: Could you explain modal analysis for me?
