Parameters Influencing Seismic Structural Collapse with Emphasis on Vertical Accelerations and the Possible Related Risks for New and Existing Structures in the Central and Eastern United States
… the lateral ground motion scales, and the vertical ground motion scales. From the parameter study, it was found that the post-yield stiffness ratio augmented by P-Delta effects (rp) in conjunction with the ductility demand was the best predictor of collapse. These two quantities include all …

SEISMIC ANALYSES OF SLOPE STABILITY AND LIMITING EARTH PRESSURES ACTING ON RETAINING STRUCTURES
… signal is characterized by horizontal and vertical accelerations, in terms of pseudo-static and pseudo-dynamic approaches. Pseudo-dynamic solutions of seismic slope stability and active/passive earth pressures are in a sense more meaningful than the pseudo-static. Centrifuge modelling (with …

Numerical and experimental investigation of the effect of an inverted bow on the hydrodynamic performance of Navy combatant hull forms
… are characterized in terms of pitch, heave, and vertical accelerations. A numerical verification and experimental validation of the seakeeping code Aegir was conducted using the inverted bow.

Modeling of the human head/neck system using rigid body dynamics
… aircraft in flight places dangerously large vertical acceleration forces on the body of the member. The additional mass on the head due to Night Vision Goggles and Helmet Mounted Displays increases the vulnerability of the head/neck system to injury. To eliminate the need for human testing, …

Detection of oceanic convection utilizing submarine-observed acceleration
… by comparing actual submarine observations of vertical velocity with vertical velocity of a hypothetical submarine driven through a field of oceanic turbulence predicted by Large-Eddy Simulation (LES). The actual submarine data included time series of three-dimensional acceleration and …

Numerical Solution of the One-dimensional and Cylindrical Serre Equations for Rapidly Varying Free Surface Flows
… in the water surface. These changes produce vertical acceleration of the fluid particles. These vertical accelerations manifest as a series of oscillating waves, called dispersive waves, which follow abrupt changes in the water surface. These dispersive waves can have a significant influence …

A Physics-Informed, Data-Driven Framework for Spatially Resolved Motion Sickness Prediction on The SA Agulhas II
… longitudinal positions. From these responses, vertical accelerations were derived and frequency weighted in accordance with 1SO 2631-1 {1997} to compute the corresponding estimated MSDV values. The framework's estimated MSDVs underwent a comparative evaluation, benchmarked against encountered …

Seismic hazard analysis and seismic slope stability evaluation using discrete faults in northwestern Pakistan
… of Ground Motions Project. Peak ground accelerations for Kaghan and Muzaffarabad which are surrounded by major faults were predicted to be approximately 3 to 4 times greater than estimates by previous studies using diffuse areal source zones. Seismic hazard maps for PGA and spectral …

Nonlinear Analysis of Multistory Structures Using "NONLIN"
During the months I have been at Virginia Tech, I have experienced the most exciting time of my life. There are many persons who helped me to pursue my Master's degree. I would like to take this opportunity to express my appreciations to them. I would like to thank my advisor and committee …

Development of an efficient fluid-structure interaction model for floating objects
… dimensions are significantly larger than the vertical dimension, we started by employing the shallow water equations, which are based on the assumption of hydrostatic pressure. The discretization was carried out taking only the nonlinear advective terms explicitly while the pressure terms are …
