Testing and evaluation of flexural reinforcing bars terminating in columns

Creator:: Koester, Carl C.
Abstract:: Capacity of transverse 1950's vintage reinforced concrete deck girder bridge bent caps with large straight bar anchorages were investigated and evaluated. Eleven subassemblage column specimens were examined with different anchorage lengths, bar groupings, amount of transverse steel, and externally applied axial force. Test results showed an increase in anchorage capacity...

Mapping Nearshore Bathymetry with Spaceborne Data Fusion and State Space Modeling

Creator:: Forfinski-Sarkozi, Nicholas A.
Abstract:: Despite numerous techniques for measuring and estimating water depth, bathymetry in the nearshore zone is notoriously difficult to map. Dangerous sea states, noisy environmental conditions, and expensive survey operations, particularly in remote areas, contribute to the difficulties of obtaining data along the coast. Global datasets, derived mainly from satellite altimetry...

Radiometric Calibration of EAARL‐B Bathymetric Lidar Data

Creator:: Wilson, Nicholas C.
Abstract:: The Experimental Advanced Airborne Research Lidar ‐ B (EAARL‐B), which was built and deployed by the U.S. Geological Survey (USGS) in 2014, is a novel topographic‐bathymetric lidar system. While retaining a number of features that were pioneered in the original National Aeronautics and Space Administration (NASA) EAARL system (e.g., low...

Flexural steel anchorage performance at diagonal crack locations

Creator:: Triska, Mary Ann
Abstract:: Large numbers of reinforced concrete deck girder bridges that were constructed during the interstate system expansion of the 1950s have developed diagonal cracking in the stems. Compared to the present AASHTO-LRFD standards, the provisions of the 1950s allowed for higher shear stress in the concrete, thus reducing the amount of...

New Simulation and Fusion Techniques for Assessing and Enhancing UAS Topographic and Bathymetric Point cloud Accuracy

Creator:: Slocum, Richard K.
Abstract:: Imagery acquired from unmanned aircraft systems (UAS) and processed with structure from motion (SfM) – multi-view stereo (MVS) algorithms provides transformative new capabilities for surveying and mapping. Together, these new tools are leading to a democratization of airborne surveying and mapping by enabling similar capabilities (including similar or better accuracies,...

Evaluation of Stereoscopic Camera Systems for Non-Intrusive Spatial Free Surface Measurement in Coastal Research Laboratories

Creator:: O'Day, Christopher S.
Abstract:: Physical modelling is instrumental to the progression of coastal engineering research and our understanding of the offshore and nearshore environments. Scaled models are designed and built to be tested in coastal research laboratories, where a wave basin or flume generates the desired wave conditions for experimentation. The surrounding hydrodynamics of...

High-cycle fatigue response of diagonally-cracked conventionally reinforced concrete bridge girders

Creator:: Lee, Ae-young S.
Abstract:: The behavior of stirrups engaged by diagonal cracks and under service loads is largely unknown. Full-size laboratory specimens were loaded to induce diagonal cracks and subjected to high-cycle fatigue loading to represent a service life of 50 years. Tests indicated little change in the average stirrup stress range and mean...

A novel framework for uncertainty propagation in river systems based on performance graphs using two-dimensional hydrodynamic modeling

Creator:: Gifford-Miears, Christopher H.
Abstract:: This thesis presents a novel approach for propagation of uncertainty in river systems. Errors in data observations and predictions (e.g., stream inflows), in model parameters, and resulting from the discretization of continuous systems, all point to the need to accurately quantify the amount of uncertainty carried through the modeling process....

Design and environmental performance of near-surface mounted carbon fiber reinforced polymer strips for shear strengthening reinforced concrete bridge girders

Creator:: Goebel, Jacob Hans
Abstract:: During the interstate expansion of the 1950s, many conventionally reinforced concrete deck girder bridges were built throughout the country. These now vintage bridges commonly exhibit diagonal cracking and rate inadequately for shear, thus they are candidates for shear strengthening to extend their useful life. Near-surface mounted (NSM) retrofitting is a...
