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.
For any cycle i, the equivalent viscous damping zeq can be calculated using the following relation (Abdelsamine and Tom, 2010): Where: the area within the inelastic force- displacement response curve denoted by ED, is a measure of the hysteretic damping or energy dissipation capacity of the member and ES depicts the recoverable elastic energy stored in an equivalent linear elastic system.
