Abstract

Journal of Vibration and Control, Ahead of Print.
Closed-form dynamic stiffness (DS) formulations are developed for exact dynamic analysis of complicated damped beam structures with internal hinges and generalized boundary conditions (BCs). The damping effects are considered by introducing both the ...
