Developing Extended Strands in Girder-Diaphragm Connections for Positive Moment Resistance
Tsvetanova Tsvetanova, KristinaIn bridges with precast prestressed concrete girders, the resistance to seismic effects is achieved by the interaction between the columns, the cap beam and the girders. Said components must be connected such that flexural ... -
Drilled Shaft Socket Connections for Precast Column in Seismic Regions
Tran, Hung Viet (2012-09-13)Conventional cast-in-place method in bridge construction requires long on-site construction time and substantial labor in the field, which can result in high construction costs and traffic delays. Using precast bridge ... -
Drilled Shaft Socket Connections for Precast Columns in Seismic Regions
Tran, Hung VietA new type of connection between a precast concrete column and a drilled shaft has been developed for Accelerated Bridge Construction (ABC) in regions of moderate or high seismicity. This connection can be built quickly ... -
Effects of Accelerated Curing on the Time-Dependent Properties of Concrete
Johannsson, IngimarThe long-term creep and shrinkage behaviors of concrete can greatly affect the serviceability and constructability of prestressed concrete structures. To account for these effects, it is necessary to reliably predict the ... -
Evaluation of the Shear Strength of Ultra-High Performance Concrete
Voytko, Danielle MUltra-High Performance Concrete (UHPC) is a cementitious concrete with reinforcing fibers that has exceptionally high compressive, tensile, flexural, and bond strengths, but not much is known about its shear strength. It ... -
Modeling of Creep in Hot-cured Concrete Used in Prestressed, Precast Bridge Girders
Magnusson, Kristjan SteinnConcrete fabricators, contractors and designers need accurate predictions of time-dependent deformations of concrete, such as creep and shrinkage. This is especially true for fabricators of precast, prestressed bridge ... -
Prediction of Time-Dependent Stresses and Deflections in Prestressed, Concrete Girders: From Start of Fabrication to End of Service Life
Davison, William Leander (2014-04-30)Fabricators and contractors need accurate prediction of the camber in precast, prestressed, concrete girders. Large differences in the camber between adjacent girders lead to significant construction difficulties that often ... -
Rocking Connection between a Precast Bridge Column and Cap Beam
Kennedy, BryanTraditional cast-in-place, concrete bridge construction is often a lengthy undertaking, which is burdensome to the motoring public because of the traffic delays that it causes. Precast construction can accelerate the ... -
Seismic Evaluation of Hollow Core Prestressed Concrete Bridge Column-Piles in Washington State
Tardieu, TashaThe Washington State Department of Transportation (WSDOT) began a bridge seismic retrofit program in 1990 in order to address the earthquake risks associated with state-owned bridges. The majority of these bridges were ... -
Seismic Performance of Column-to-Drilled-Shaft Connections in Reinforced Concrete Bridges
Chang, Michelle TengDrilled shaft foundations are often used to support reinforced concrete bridge columns founded in soft soils or in locations where a small footprint is desired. Increasingly, the shaft is being built with a diameter larger ... -
SHEAR STRESS TRANSFER ACROSS CONCRETE TO CONCRETE AND STEEL TO CONCRETE INTERFACES
Davaadorj, OtgonchimegAbstract This research project investigates shear transfer across concrete-to-concrete and steel-to-concrete interfaces where “sliding shear” failure is critical. Experimental data available in the literature were collected ... -
Specialized Track Bridge Structure for Light Rail Construction on Floating Bridges
Thonstad, Travis Edward (2013-07-23)Sound Transit's East Link Light Rail project carries light rail transit (LRT) to east King County Washington over the existing Homer M. Hadley Memorial Bridge. Although there are examples of similar projects on cable-stayed ... -
Unbonded Pre-tensioned Bridge Columns with Hybrid Fiber-Reinforced Concrete Shells
Finnsson, Gunnsteinn (2013-07-23)Many bridges in the United States are getting old and will need to be replaced in the near future. If these bridges are constructed with conventional cast-in-place methods, this construction will cause traffic congestion, ...
