An Independent-Flow-Field Model for a SDOF Nonlinear Structural System–Part II: Analysis of Complex Responses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Complex responses observed in an experimental, nonlinear, moored structural system subjected to nearly periodic wave excitations are examined and compared to the simulations of a newly proposed ...
An Independent-Flow-Field Model for a SDOF Nonlinear Structural System–Part I: Identification and Comparisons
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An independent-flow-field (IFF) model selected in this study to investigate the nonlinear response behavior of a medium-scale, experimental, submerged, moored structure is validated via parametric ...
Estimation of Cascadia Local Tsunami Loads on Pacific Northwest Bridge Superstructures
Publisher: American Society of Civil Engineers
Abstract: The time histories of Cascadia Subduction Zone (CSZ) local tsunami horizontal and vertical loads and the overturning moment on four selected Oregon coastal bridges are computed for different load scenarios. These scenarios, ...
Coupled Surge-Heave Motions of a Moored System. II: Stochastic Analysis and Simulations
Publisher: American Society of Civil Engineers
Abstract: Analyses and simulations of the coupled surge-and-heave motions of a nonlinear, moored, experimental, submerged structure subjected to random waves are presented here. The random wave excitations examined include periodic ...
Coupled Surge-Heave Motions of a Moored System. I: Model Calibration and Parametric Study
Publisher: American Society of Civil Engineers
Abstract: Model calibration and parametric studies of the coupled, complex surge-heave motions of a medium-scale experimental, nonlinear, submerged, moored structural system are presented here. The experimental system excited by ...
A Nonlinear Three-Dimensional Coupled Fluid-Sediment Interaction Model for Large Seabed Deformation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A nonlinear three-dimensional two-way coupled fluid-sediment interaction model is developed in this study. The model is composed of a generalized Navier–Stokes solver (GNS) with a volume of fluid ...
Proper Orthogonal Decomposition of Pressure Field in Sloshing Impact
Publisher: American Society of Civil Engineers
Abstract: To evaluate the predictive capability of the proper orthogonal decomposition (POD) in approximating dynamics of wave impact, the method is applied to the special case of sloshing problems that are widely found in engineering ...
Stochastic Control of Sensitive Nonlinear Motions of an Ocean Mooring System
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Complex sensitive motions have been observed in ocean mooring systems consisting of nonlinear mooring geometries. These physical systems can be modeled as a system of first-order nonlinear ordinary ...
FNPF Analysis of Stochastic Experimental Fluid-Structure Interaction Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A two-dimensional fully nonlinear potential flow model is employed to investigate nonlinear stochastic responses of an experimental fluid-structure interaction system that includes both single-degr ...
A Three-Dimensional Coupled Fluid-Sediment Interaction Model With Bed-Load/Suspended-Load Transport for Scour Analysis Around a Fixed Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The predictive capability of a three-dimensional (3D) numerical model for sediment transport and resulting scour around a structure is investigated in this study. Starting with the bed-load and ...
