In the case of steel moment-frame buildings, the nonlinear behavior of beam-column connections significantly affects the dynamic response under earthquakes since connection regions are one of the primary sources of hysteretic damping.
Other topics include dynamic analysis of lower limb prosthesis, noise control in an industrial hall, hysteretic damping of elastomeric systems, and vibration in an engine with neo-Hookean suspension.
Due the hysteretic damping behavior, it is difficult to model using conventional finite element analysis (FEA) approaches.
The state-of-the-practice involves carrying out preliminary calculations and analyses using typical HDR bearings or LRB which provide a moderate amount of hysteretic damping.
In the frequency domain, hysteretic damping can be introduced using the correspondence principle and by replacing the stiffness matrix [K.
