Stochastic analysis of a nonlinear ocean structural system

Creator:: Lin, Huan
Abstract:: Stochastic analysis procedures have been recently applied to analyze nonlinear dynamical systems. In this study, nonlinear responses, stochastic and/or chaotic, are examined and interpreted from a probabilistic perspective. A multi-point-moored ocean structural system under regular and irregular wave excitations is analytically examined via a generalized stochastic Melnikov function and Markov...

Chaotic response and stability of offshore equipment

Creator:: Lin, Huan
Abstract:: This investigation deals with the chaotic rocking response and overturning stability of offshore equipment subjected to base excitations due to wave-induced motions of the supporting compliant offshore structural system. The equipment compliant structural system is modelled as a free-standing rigid object subjected to horizontal and vertical base accelerations. Three of...

The analysis of directional wave spectra from current and pressure measurements

Creator:: Lin, Li-hwa
Abstract:: Directional wave spectra have been estimated in this study based upon simultaneous subsurface measurements of current and pressure. Two previously developed methods, the stochastic and deterministic approaches, have been reviewed and restudied. It is demonstrated by means of the Correlation Theorem that the stochastic and deterministic approaches are, under certain...

A Regional-Scale Three-Dimensional Susceptibility Model for Enhanced Evaluation of Rainfall- and Seismically-Induced Landsliding

Creator:: Mathews, Nicolas
Abstract:: Shallow landslides are destructive natural hazards that result in widespread losses, both of infrastructure and lives, throughout the world. To help mitigate the impact of landslide hazards, they are commonly characterized across a regional scale by (1) their location and likelihood using susceptibility maps, (2) their magnitude and frequency using...

Numerical simulation of mechanically stabilized earth walls for parametric evaluation of behavior under surcharge loading

Creator:: Ambauen, Spencer J.
Abstract:: A numerical model, simulating the complex behavior of reinforced soil walls using the finite element method, was developed to evaluate the behavior of a surcharged, geosynthetic-reinforced retaining wall with modular block facing. A nonlinear elastic-plastic constitutive soil material model was calibrated to experimental plane strain test data, while the performance...

New Techniques to Monitor and Characterize Landslide Behavior and Controls Using Digital Terrain Models

Creator:: Senogles, Andrew
Abstract:: Coastal landslides and erosion are major natural hazards resulting in unstable slopes, constituting immense challenges to modern infrastructure. Developing, maintaining, and performing risk assessments of infrastructure on, or close to, these hazards require a detailed understanding of the geophysical processes destabilizing the slope. These efforts start with the collection of...

Evaluation and Modification of a Thixotropic Fluid Model for Liquefaction Triggering with Application to Laboratory Tests and Lateral Spreading

Creator:: Brown, Tovey M.
Abstract:: Earthquake-induced liquefaction is a large contributor to damage observed following seismic events. Commonly observed damage consists of significant ground and structural failure due to the deformation of large volumes of soil due to soil liquefaction and lateral spreading. A significant focus of geotechnical seismic research concentrates on the development and...

Numerical response of concrete-lined tunnels crossing active faults

Creator:: Lange, Stephanie
Abstract:: A challenge for municipal authorities of growing urban areas is to provide larger and faster transportation and utility networks that are safe and resilient to significant disruptions after an earthquake event and other disasters. Urban regions, like the San Francisco Bay or the Los Angeles area, are situated in seismically...
