High Strength Reinforcing Bars : Concrete Shear Friction Interface Behavior

Creator:: Nielson, Drew R.
Abstract:: Use of high-strength steel (HSS) reinforcing bars could provide constructability and economic benefits for the construction of structures, reducing the initial and ultimately the life-cycle cost of bridge and building structural elements. This thesis summarizes work performed in a research project on the use of HSS reinforcing bars for concrete...

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...

Effect of vertical compressive stress on shear strength of wood beams

Creator:: Mandery, William Lee
Resource Type:: Dissertation

Designing a strand orientation pattern for improved shear properties of oriented strand board

Creator:: Alldritt, Kenton
Abstract:: As oriented strand board (OSB) increases in use as an engineered wood product, improving the in-plane shear properties will allow more efficient use of the material as well as open up other opportunities for OSB to be used in engineered wood products with high shear stresses. Based on classical laminated...

Analysis of conventionally reinforced concrete deck girder bridges for shear

Creator:: Potisuk, Tanarat
Abstract:: Large numbers of 1950's vintage conventionally reinforced concrete (CRC) bridges remain in-service in the national bridge inventory. Many of these bridges are lightly reinforced for shear. Evaluation of these bridges to prevent unnecessary and costly repairs requires refined analytical techniques. This dissertation presents finite element (FE) modeling and comparisons of...

Analysis of conventionally reinforced concrete bridge girders for low-cycle fatique in shear

Creator:: Forrest, Richard W. B.
Abstract:: Increasing load magnitudes and loss of reinforcing steel cross-sectional area from corrosion creates the potential for low-cycle fatigue (LCF) in conventionally reinforced concrete (CRC) bridge girders lightly reinforced for shear. LCF of reinforcing steel may be of particular concern. Little data are available for LCF of reinforcing steel without stress...

Reliability based bridge assessment using modified compression field theory and Oregon specific truck loading

Creator:: Daniels, Theresa Kathryn
Abstract:: Assessment of an existing bridge is needed when the structure exhibits signs of distress. Assessment practices require refinement in the calculation of loading and resistance while maintaining an acceptable level of risk, to minimize costs associated with repair, replacement and weight restrictions. Previous risk-based assessments evaluated the strength cases for...

Design and fatigue behavior of near-surface mounted CFRP bars for shear strengthening of RC bridge girders

Creator:: Johnson, Brandon Ang
Abstract:: Carbon fiber reinforced polymer (CFRP) materials are emerging as an effective means of strengthening and rehabilitating bridges. Near surface mounting (NSM) is a newer technique for application of CFRP for retrofitting of bridge members that provides advantages over conventional strengthening techniques. The technique is still new and uncertainties remain regarding...

The performance of wood frame shear walls under earthquake loads

Creator:: White, Kevin Bradish DelGrande
Abstract:: The overall goal of this study is to evaluate the earthquake performance of wood frame shear walls, and more specifically: (1) to compare the performance differences of fully and partially anchored walls under monotonic, cyclic, and earthquake loads, (2) to compare wall performance under earthquake loads with that of standardized...

Shear repair methods for conventionally reinforced concrete girders and deep beams

Creator:: Howell, Daniel A.
Abstract:: Many conventionally reinforced concrete deck girder bridges (RCDG) and their intermediate supporting bent caps were designed during the Eisenhower interstate era of the 1950’s with the AASHO design equations at the time, which subsequently place higher demand on the concrete. The referenced components may exhibit diagonal cracking due to the...

Scale effects on reinforced concrete beams strengthened for shear with discrete externally bonded carbon fiber-reinforced polymer U-wraps

Creator:: Dawson, Matthew Ryan
Abstract:: Current ACI design provisions for shear in reinforced concrete (RC) beams strengthened with externally bonded carbon fiber-reinforced polymer (CFRP) U-wraps may not adequately account for the effect of scale. This paper describes tests of 6 geometrically scaled beams to identify possible scale effects of such beams. Results indicated that effective...

Strain distribution in OSB and GWB in wood frame shear walls

Creator:: Sinha, Arijit
Abstract:: The overall goal of this study was to gain an insight into the load sharing aspect between oriented strand board (OSB) and gypsum wall board (GWB) in shear wall assembly during racking load. More specifically the objectives of the study were to: (1) evaluate qualitatively the load sharing between OSB...
