The Dynamics Of Mixing And Subtidal Flow In A Maine Estuary, Kristopher Bears
The Dynamics Of Mixing And Subtidal Flow In A Maine Estuary, Kristopher Bears
Electronic Theses and Dissertations
Long-term material transport in estuaries is largely controlled by subtidal flow. Subtidal flows are driven by conditions specific to their geographic location, namely river discharge, tidal forcing, and wind. These conditions are further modified by mixing, curvature of the estuary, Coriolis, and friction. While many practices of measuring these various forcing mechanisms exist, the current literature fails to provide a standard for measuring turbulent mixing in well- mixed estuaries. As a changing climate affects these various forcing and modifying mechanisms via sea level rise and increased precipitation, the corresponding material transport scheme is expected to change accordingly. Subtidal flow and …
Evaluation Of Non-Composite Steel Girder Bridges Using Field Load Testing And A Calibrated Finite-Element Model, Mahmood J. Albraheemi
Evaluation Of Non-Composite Steel Girder Bridges Using Field Load Testing And A Calibrated Finite-Element Model, Mahmood J. Albraheemi
Electronic Theses and Dissertations
This research focuses on understanding the behavior of five, non-composite, simple-span steel girder bridges using field load testing and calibrated finite element models. These bridges were tested during the summer of 2016. Strains and selected displacements were measured at multiple locations during the field load tests. 3D finite-element (FE) models were created to simulate the actual response of these bridges with a novel approach to calibrate these models was developed that captures the observed full and partial composite action as well as rotational restraint of the girder ends. More accurate predictions of the bridges capacity were determined using field tests. …
