Twenty Years of Structural Dynamic Modification – A Review
نویسنده
چکیده
Structural dynamic modification techniques have been available as a design tool for several decades. This article reviews the methodology of the technique including both proportional and complex mode formulations. Issues pertaining to limitations on their use and truncation effects of unmeasured modes are discussed. Also discussed is the use of simplistic elements through higher order elements. Discussion on typical commercial implementations is presented. Finally, the ever-constant problems with lack of rotational DOF and truncation are presented, as well as attempts to overcome those issues.
