Abstract: During an earthquake, freestanding equipment and contents in a building may experience large complex 3D motion. Depending on the geometry, mass distribution, and support mechanism (e.g., wheels, casters, legs) of the object, ...

Abstract: 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 ...

Abstract: Base isolation is accepted as the method of choice for mitigating the seismic risk of critical facilities, including hospitals. However, while many studies have confirmed the effectiveness of isolation in reducing seismic ...
