Abstract: This study presents results from cyclic testing on various configurations of a recently developed pressurized sand damper in which a steel sphere is moving within a cylindrical tube filled with sand that is under pressure. ...

Abstract: This study presents the mathematical characterization of the recently developed pressurized sand damper (PSD) in which a steel sphere or bolt is moving within a cylindrical tube filled with sand under pressure. The ...

Abstract: Seismic isolation is an effective measure for mitigating earthquake hazard on important structures such as bridges, hospitals, and nuclear power plants. Seismically isolated structures should remain essentially elastic for ...

Abstract: This paper presents a discrete element method (DEM) numerical model to elucidate mechanical behavior, particle crushing, and anisotropy evolution within a pressurized sand damper (PSD) subjected to cyclic loading. Computational ...
