3-D finite element modeling in OpenSees for bridge live-load girder distribution factors

Creator:: Scoggins, Luke A.
Abstract:: A generalized, three-dimensional, finite element bridge model was created in order to efficiently and accurately assess live-load girder distribution factors for a variety of bridge types. This model shortens the time required by bridge analysts to develop individual finite element models for bridges of varying geometries. The creation of the...

Multi-objective Optimization of Reservoir Operation Under Uncertainty with Robust and Flexible Decision Variables

Creator:: Hosseini, Parnian
Abstract:: Optimization of reservoir operation is involves various competing objectives for a scarce resource (water). To find the optimal operation of reservoirs, it is essential to consider multiple objectives simultaneously. There are various sources of uncertainty associated with the reservoir operation problem that should be considered as well. The overarching goal...

A kinetic model for dissolved gas transport in the presence of trapped gas

Creator:: Donaldson, Jeremy H.
Abstract:: Understanding the processes involved in the transport of dissolved gas plumes in groundwater aquifers is essential for comprehending the effect that these transport processes can have on site characterization and remedial design applications. Previous laboratory and field studies have indicated that dissolved gas transport in groundwater can be greatly affected...

A procedure to identify and evaluate forest arterial and collector road networks

Creator:: Kehr, Richard H.
Abstract:: This thesis presents a procedure to identify and evaluate forest arterial and collector networks. The procedure identifies those decision criteria important in evaluating both the arterial and collector networks and the specific facilities identified on these networks. The procedure incorporates the decision criteria and results from network and facility analysis...

Image rectification tool for evaluation of gusset plate connections in steel truss bridges

Creator:: Nguyen, Quang D.
Abstract:: A methodology was developed to permit rectification and metrification of digital images of steel truss gusset plate connections. The approach will enable rapid and accurate collection of field measurements as compared to traditional methods to enable structural evaluation of gusset plate connections. The program enables the operator to quickly create...

Measuring and Correcting the Electrical Resistivity of Concrete Pore Solution in Fresh Mixtures

Creator:: Biever, Joseph H.
Abstract:: A vital aspect of concrete construction is quality assurance and control (QA/QC). Engineered structures must meet pre-determined and agreed-upon strength and durability requirements. Concrete falls into a specific category of infrastructure material because in most cases, these strength and durability requirements cannot be found until the material has at least...

Effects of reference displacement and damage accumulation in wood shear walls subjected to the CUREE protocol

Creator:: Langlois, Jeffrey D.
Abstract:: The objectives of this study are: (1) to evaluate the effect of reference displacement on wall behavior under fully reversed cyclic loading using the CUREE test protocol and (2) to assess damage accumulation (visible fastener damage and stiffness degradation) for the imposed drift levels. All tests were conducted on identical...

Roughness and geometry effects of engineered log jams on 1-D flow characteristics

Creator:: Valverde, Rachelle S.
Abstract:: The re-introduction of large woody debris (LWD) into streams and rivers for stream restoration purposes is rapidly growing. Engineered log jams (ELJs) are man-made structures intended to mimic natural LWD structures, designed and installed to protect stream banks from erosion while increasing habitat diversity. Several studies have evaluated the flow...

Adjacent structure response sensitivity to seismic events using the direct differentiation method

Creator:: White, William S.
Abstract:: The response of adjacent structural systems to earthquake motions is investigated using the finite element framework OpenSees. Results of sensitivity analyses demonstrate that structural response quantities can increase in either or both of the adjacent structures for specific configurations. The structural models used include steel moment-resisting frames and rigid shear...
