Behavior Of Buried Composite Arch Bridges, Harold J. Walton
Behavior Of Buried Composite Arch Bridges, Harold J. Walton
Electronic Theses and Dissertations
This dissertation presents experimental results and numerical analysis for short-span buried composite arch bridges whose main structural members are concrete-filled fiber reinforced polymer (FRP) tube arches (CFFTs). This investigation focuses on soil- structure interaction of the bridge system to expand understanding beyond isolated arch performance. Soil plays several roles: weight on the structure, restraining arch movement, and dissipating surficial truck loads.
Investigation focused on experimental and numerical analysis of subscale bridge systems. Four bridge systems were constructed with two different span-to-rise ratios (5:1 and 2.67:1) and two different materials (linear-elastic steel and CFFT). Tested systems were half-scaled from commercial bridge …
Correlation Of Engineering Parameters Of The Presumpscot Formation To The Seismic Cone Penetration Test (Scptu), Mathew Hardison
Correlation Of Engineering Parameters Of The Presumpscot Formation To The Seismic Cone Penetration Test (Scptu), Mathew Hardison
Electronic Theses and Dissertations
The seismic cone penetration test with pore pressure measurement (SCPTu) is a geotechnical investigation technique which involves pushing a sensitized cone into the subsurface at a constant rate while continuously measuring tip resistance, sleeve friction, and pore pressure resulting from soil shearing. Additionally, shear wave velocity measurements can be collected at discrete intervals throughout the test. Empirical and theoretical correlations have been developed between these measurements and soil engineering properties such as preconsoldiation pressure and undrained shear strength. Soil classification, location of silt/sand seams, seismic design parameters, and liquefaction potential can also be obtained from SCPTu results.
