Abstract

Dynamic characteristics of a structure are usually referred to as its natural frequencies and mode shapes. The ability to alter these characteristics in order to have desired dynamic characteristics for a structure either by design, re-design or by modification has been an enduring quest by structural analysts. The need to change dynamic characteristics of a structure may come from new design requirements, solution for excessive vibration, or the necessity to control the response of the structure. It is unrealistic and unnecessary to attempt to alter all natural frequencies or mode shapes of a structure but selected changes via modification are possible. In many applications, it is often a part of the dynamic characteristics of a structure such as a particular natural frequency that needs to be changed.
