Effect of the Stick-Slip Phenomenon on the Sliding Response of Objects Subjected to Pulse Excitation

The response analysis of sliding objects and structures subjected to ground excitation is most often performed using Newmark’s rigid sliding block with Coulomb friction. This simplified sliding model has been shown to sometimes result in poor predictions of sliding displacement. In an effort to improve sliding response predictions, this paper introduces a model that relaxes the rigidity constraint of the Newmark model and takes into account …
