Influence Of Live -Load Deflections On Superstructure Performance Of Slab On Steel Stringer Bridges, Haiyong Wu Dec 2003

Influence Of Live -Load Deflections On Superstructure Performance Of Slab On Steel Stringer Bridges, Haiyong Wu

Graduate Theses, Dissertations, and Problem Reports (ETD)

High performance steel (HPS), specifically HPS 70W, was introduced to the bridge market in the United States in the late 1990s. With its added strength, greater durability, and improved weldability, HPS allows engineers to design longer and shallower spans, which may increase the live-load deflections. The AASHTO Standard Specification limits live-load deflections to L/800 for ordinary bridges and L/1000 for bridges in urban areas subjected to pedestrian use. Bridges designed by the AASHTO LRFD Specification have an optional deflection limit. Previous research focused on evaluating AASHTO live-load deflection limits showed that the justification for existing deflection limits was not clearly …

Novel Syntheses Of Indoles, Quinoxalines, 2-Quinoxalinones, 2-Alkylbenzimidazoles And Other Heterocycles, Jeffery M. Wallace

Graduate Theses, Dissertations, and Problem Reports (ETD)

Using a palladium-catalyzed reductive N-heteroannulation method previously discovered in our labs, a 20 mmol synthetic route to methyl indole-4-carboxylate has been developed. Methyl indole-4-carboxylate is synthesized in four steps, with the key step being the reductive cyclization of methyl 2-ethenyl-3-nitrobenzoate in good overall yield. This cyclization method has been modified and applied to the preparation of quinoxalines, 2-quinoxalinones and other heterocyclic compounds. We also propose a possible mechanism for these transformations.;In addition, a novel method to 2-alkylbenzimidazoles has been developed. The thermal reaction of 2-azidonitrobenzenes and various aldehydes give 2-alkylbenzimidazoles generally in moderate yield.

Potential Field Theory And Its Applications To Classical Mechanical Problems, Shannon Rae Stillwagon Dec 2003

Potential Field Theory And Its Applications To Classical Mechanical Problems, Shannon Rae Stillwagon

Graduate Theses, Dissertations, and Problem Reports (ETD)

Advances in many scientific fields are expected to come from work in nanotechnology. Engineering at nano-scales presents novel problems that classical mechanics cannot solve. Many engineers are uncomfortable designing at this level because classical or continuum mechanics does not apply and quantum mechanics is said to apply in a tangible way. There are unique opportunities to contribute to the design, controls, and analysis of systems that are particularly suited to mechanical engineering. Within the derivations of classical mechanics are assumptions that limit its use to bulk engineering. These assumptions are examined to determine what principles can be extended to smaller …

Identity Formation Of Adolescents Involved In Selected Structured Activities, Sara A. Drake Dec 2003

Identity Formation Of Adolescents Involved In Selected Structured Activities, Sara A. Drake

Graduate Theses, Dissertations, and Problem Reports (ETD)

Identity formation is seen as the primary developmental task during adolescence according to Erikson (1968). Adolescents' involvement in structured activities such as extracurricular activity, 4-H, and volunteerism were examined to determine their associations with identity formation. Researcher James Marcia (1966) developed four statuses of identity formation: diffusion, foreclosure, moratorium, and achieved. Categorization in one of the four statuses depends upon the levels of both crisis and commitment. Adolescents who are in the identity-diffused category have had no crisis or made no commitment. Those who foreclose, have made a commitment, but have had no crisis. Moratorium is a state of exploration, …
