Analysis of diagonally cracked conventionally reinforced concrete girders in the service load range

Creator:: Robelo, Melissa J.
Abstract:: Performance evaluation of conventionally reinforced concrete (CRC) bridge superstructure elements with diagonal cracks is of interest to the bridge engineering community. Standardized methods to predict service-level stress magnitudes in cracked bridge girders under combined bending and shear forces are not available. An analysis procedure was developed to determine the response...

Investigation of the behavior of diagonally cracked full-scale CRC deck-girders injected with epoxy resin and subjected to axial tension

Creator:: Smith, Matthew T. (Matthew Todd)
Abstract:: Article 1: Behavior of Epoxy Injected Diagonally Cracked Full-Scale CRC Deck-Girders. Many cast-in place reinforced concrete deck-girder bridges (RCDG) remain in the national inventory and exhibit diagonal cracking. Epoxy injection has been in use for several decades as a method for sealing diagonal cracks, but the effects on girder behavior...

Influence of diagonal cracks on negative moment flexural anchorage performance in reinforced concrete bridge girders

Creator:: Goodall, Joshua K.
Abstract:: Large numbers of vintage reinforced concrete deck-girder bridges remain in the national bridge inventory. Many of these exhibit diagonal cracking and other distress. Due to the design practices of the time, it is common to observe cracks at locations where flexural reinforcing steel is terminated along the span. The presence...

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...

Innovative Strategies to Protect Concrete Bridge Decks and Cross-Laminated Timber Structures through the Use of Impermeable Overlays

Creator:: Haynes, Matthew A.
Abstract:: Bridges are a vital component of transportation infrastructure in the United States, and the continual maintenance and preservation of bridges is critical to maintaining their structural capacity and maximizing service life. One of the most significant issues faced by concrete bridges is the infiltration of moisture from the roadway surface...

Assessing the seismic performance of corroding RC bridge columns

Creator:: Guo, Yisen
Abstract:: Corrosion of reinforcement is recognized as the predominant factor that limits the service life of reinforced concrete (RC) structures exposed to aggressive environments. This corrosion deterioration can lead to damage resulting in capacity loss or even failure. For structures exposed to coastal marine environments or deicing or anti-icing applications, this...

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...

Seismic Performance of Square Reinforced Concrete Columns Retrofitted with Titanium Alloy Bars

Creator:: Lostra, Mackenzie M. W.
Abstract:: Large numbers of reinforced concrete (RC) bridges were built in the past that are now considered seismically deficient. The structural members most likely to be considered deficient are the supporting columns. Typical deficient columns contain inadequate transverse reinforcement and poorly detailed lap splice lengths above the foundation. Insufficient lap splice...

The use of blended synthetic fibers to reduce cracking risk in high performance concrete (HPC)

Creator:: Bañuelos, José
Abstract:: High Performance Concrete (HPC) is used in our crucial pieces of infrastructure, such as bridge decks, due to its enhanced durability and engineering properties. However, HPC is highly susceptible to early-age cracking. Cracking within the first months of a bridge deck’s lifespan can severely hinder its long-term performance and durability....

A torsional investigation of a concrete I grider

Creator:: Martin, Roy Charles
Abstract:: This paper investigates a particular bridge construction technique which could result in a significant torsional moment. The structural member under consideration is a prestressed concrete girder for which no torsional consideration is made. Torsional shear stresses can be adequately approximated for an I-shaped girder. Laboratory model tests were performed to...
