of sands under cyclic loading and its relation to shear modulus.
Design procedures for buildings incorporating 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
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.
Frictional resistance among the members of the joints caused by pretension substantially increased the initial slip resistance and hysteretic damping.
04 rads was arbitrarily chosen to examine the influence of pretension force on hysteretic damping of the joints.
In the frequency domain, hysteretic damping
can be introduced using the correspondence principle and by replacing the stiffness matrix [K.
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
Inter storey drifts are also reduced as hysteretic damping
is provided by lead core of lead rubber bearing.
The nail reinforcements contribute to the increase of hysteretic damping
or area enclosed by the loop of the bolted joints though pinching behavior or narrowing the loop close to zero rotation points is still observed.
