Valuable bridges : cable-stayed bridges and value engineering in American civil engineering culture, 1969-1979
A history and theory of cable-stayed bridges in the context of a cultural discourse on civil construction projects' value, this thesis studies the significance of cable-stayed bridge designs to 'value engineering' objectives for major highway bridge projects of the 1970s. This study of preliminary …

Optimum design of precast bridge systems prestressed with carbon fiber reinforced polymers
… rapidly growing and has exciting applications in bridge construction. These materials are light, have an excellent resistance to corrosion, and high strength. Because of these advantageous properties, structures reinforced with composite materials are lighter and have longer service life than …

Interface Shear Strength in Lightweight Concrete Bridge Girders
… decks are a typical type of concrete bridge construction. A key part of this type of construction is developing composite action between the girder and deck. In order to develop composite action, adequate horizontal shear resistance must be provided at the interface. As lightweight …

Parametric analysis of resilient design of steel truss bridges
… design has been particularly prevalent in bridges. The failures have been results of a variety of factors that the bridges have been subjected to. The objective of preventing the occurrence of future collapses has encouraged further research into the design of resilient structures. Two main …

Optimization of Highway Bridge Girders for Use with Ultra-High Performance Concrete (UHPC)
… desirable material for the production of highway bridge girders. However, UHPC's unique constitutive materials make it more expensive than conventional concrete. The cost and lack of appropriate design guidelines has limited its introduction into bridge products. The investigation presented in …

Characterization and Modeling of a Fiber-Reinforced Polymeric Composite Structural Beam and Bridge Structure for Use in the Tom's Creek Bridge Rehabilitation Project
… for steel and concrete in primary and secondary bridge structures, but the experience with composites in these applications is minimal. Recently, however, a number of groups in the United States have constructed short-span traffic bridges utilizing FRP members. These demonstration cases will …

Effect of Thermal Loading on the Performance of Horizontally Curved I-Girder Bridges
… and older infrastructure is replaced or updated, bridge designers are faced with increasing space and geometrical limitations. Curved bridges have become a popular design alternative to the traditional straight girder or chorded bridges as they can provide the designer a more cost effective …

Evaluation of Novel Laser-Skived Microbridges for Improved Characterization of REBCO Superconductor
… performance. Two downsides are the traditional bridge manufacturing process and the potential for the bridge to sample regions of higher or lower than width-averaged critical current. Bridging is traditionally achieved through a process of chemical etching and photolithography, which is labor …

Lateral load distribution for steel beams supporting an FRP panel.
… to concrete decks when replacing deteriorated bridges. The main advantages of an FRP deck are its weight (roughly 75% lighter than concrete), its high strength-to-weight ratio, and its resistance to deterioration. In bridge design, AASHTO provides load distributions to be used when determining …

Distribution, population status and conservation of the samango monkey (Cercopithecus albogularis schwarzi) in the Limpopo Province, South Africa
… to test the suitability of two different canopy bridge designs through field experimentation and behavioural data collection for arboreal guenon roadkill mitigation. Analysis of actual roadkill data collected in the study area provided insights into the nature of high-risk localities. We showed …
