Applying climate change information to hydraulic and hydrologic transportation infrastructure

Creator:

Al Naabi, Rawan Y.

Abstract:

Scour is the main cause of bridge failures in the United States. Bridge failures raise a hazard to the safety of the traveling public as well as the massive economic consequences due to the high cost of constructing a new or a replacement bridge. The Oregon Department of Transportation (ODOT)...

Experimental and Analytical Studies of Large-Scale Pile Caps

Creator:

Al-Sakin, Yasmeen

Abstract:

Pile caps are structural elements used to transfer loads from columns to a group of piles, which transfer them to stronger soil layers. Pile cap with horizontal distance between the column and piles less than twice its effective depth is categorized as "deep," where significant nonlinear strain distribution occurs through...

Experimental research on the behavior and strength of large-scale steel gusset plates with sway-buckling response including effects of corrosion and retrofit options

Creator:

Hafner, Anthony G.

Abstract:

The collapse of the I-35W Bridge in Minneapolis, MN on August 1, 2007 brought into question the design and inspection of gusset plates in steel truss bridges. The experimental tests performed in this research study the sway-buckling strength and behavior of large-scale steel gusset plates in an isolated truss connection....

Non-destructive determination of yield stress for in-situ gusset plates

Creator:

Pflaum, Therese Michelle

Abstract:

Failure of a gusset plate that caused the I-35W Bridge collapse in Minneapolis, MN resulted in mandated rating of connections by the Federal Highway Administration (FHWA). Rating connections requires material properties as an input. The material properties are generally reported on the available detailed drawings for bridges. However, some bridges...

Wind induced torsional fatigue behavior of truss bridge verticals

Creator:

Keller, Philipp

Abstract:

The Astoria-Megler Bridge is a 6.6 kilometer (4.1 mile) long bridge, connecting Oregon and Washington on US 101, with a continuous steel truss main span of 376 m (1232 ft). It is the second longest main span bridge of this type in the world. Due to vortex shedding, some of...

Behavior of open grid steel bridge decks under service and fatigue loads

Creator:

Fetzer, Peter C.

Abstract:

Open grid steel bridge decks have been in use for nearly a century. These open grid decks provide an economical and lightweight alternative to traditional reinforced concrete decks. As the transportation infrastructure continues to deteriorate, open grid decks can be used as a cost effective way to rehabilitate structurally deficient...

Shear strengthening reinforced concrete bridge girders using near-surface mounted titanium alloy bars

Creator:

Knudtsen, Jonathan

Abstract:

Aging and deficient infrastructure has become a major problem throughout the world. This is particularly evident in the case of reinforced concrete (RC) bridges. The cost of replacing these bridges is often prohibitive, thus engineers must find ways to strengthen them. Many older RC bridges predate the modern understanding of...

Seismic Performance of Aging Prestressed Transmission Pole with Simulated Soil Foundation

Creator:

Argo, Maximo

Abstract:

The Cascadia Subduction Zone has recently been identified as a source for an impending great earthquake. The potential of a large earthquake has created widespread interest into the resiliency of lifelines within the potentially affected areas. One critical lifeline is the electrical distribution and transmission systems which relies on legacy...

Flexural anchorage performance and strengthening on negative moment regions using near-surface mounted retrofitting in reinforced concrete bridge girders

Creator:

Barker, Laura

Abstract:

Large numbers of reinforced concrete deck girder (RCDG) bridges were built during the highway infrastructure boom of the 1950's. The advent of standardized deformed steel reinforcing bars during this time allowed for straight bar terminations in flexural tension regions. Designers of the time terminated reinforcing bars where they were no...

Application of Titanium Alloy Bars for Strengthening Reinforced Concrete Bridge Girders in Flexure

Creator:

Vavra, Eric

Abstract:

Structurally efficient and cost-effective solutions are needed to extend the service-life of deficient and aging highway infrastructure around the world. One critical need is to increase the flexural strength of older reinforced concrete (RC) structures to carry heavier and more frequent loads. Titanium alloy bars (TiAB) offer a new opportunity...
