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: An extensive statistical analysis is conducted on experimental data to achieve a formula for the strength and stiffness of masonry- infilled frames having central openings. For this, most of the available experimental data ...

Abstract: In this study, a new coupled surface shape design (SSD) methodology named direct design method is presented for the solution of problems containing different types of convection heat transfer in which a specific distribution ...

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 ...

Abstract: Self-formed shape and energy loss taking place at the transition of alluvial canals were studied. Two trapezoidal erodible canals were modeled along with a sudden contraction in a laboratory flume. Experiments were performed ...
