Investigating Wave Forces on Coastal Bridge Decks
… induced waves are responsible for many coastal bridge failures, especially in the last decade. In the current study, three countermeasures (reducing the entrapped air, elevating the structures and rigidifying the structures) are considered, two wave types (solitary wave theory and Stokes wave …

Service Life Modeling of Virginia Bridge Decks
… of Functional Service Life (EFSL) for concrete bridge decks in Virginia was developed. The service life of Virginia bridge decks is controlled by chloride-induced corrosion of the reinforcing steel. Monte Carlo resampling techniques were used to integrate the statistical nature of the input …

GPR data processing for reinforced concrete bridge decks
… several aspects of GPR data processing for RC bridge decks are studied. First, autofocusing techniques are proposed to replace the previous expensive and unreliable human visual inspections during the iterative migration process for the estimation of the velocity/dielectric permittivity …

Crack detection technique for reinforced concrete bridge decks
… and test results of a reinforced concrete bridge deck constructed on 3-span continuous steel girders. The instrumented bridge is located in Evansville, West Virginia at the intersection of US Route 50 East and WV 92 South. An instrumentation system is developed and implemented specifically …

Condition Analysis of Concrete Bridge Decks in Utah
Concrete bridge decks in Utah are experiencing observable deterioration due primarily to freeze-thaw cycles and the routine application of deicing salts during winter maintenance activities. Given the need for increasingly cost-effective strategies for bridge deck maintenance, rehabilitation, and …

Horizontal Shear Connectors for Precast Prestressed Bridge Decks
… convenient for rehabilitation of deteriorated decks as well as for new bridge construction. The horizontal shear strength at the interface between the two interconnected elements is of primary importance in order to provide composite action. The strength of the bond between the two precast …

Durability studies of high performance concrete used for bridge decks
The present study, as a part of the WVDOH large scale project on HPC, was directed to evaluate various durability aspects of HPC using West Virginia (WV) sources of materials. A total of 24 HPC mixtures were prepared with different supplementary cementing materials (SCM), such as fly ash, slag, …

Mitigation of early age cracking of concrete for bridge decks
… longer service life when considering concrete bridge decks for highway applications. Service life of concrete bridge decks is often cut short indirectly, due to deterioration mechanisms that exist at early ages of the concrete. Early age deterioration mechanisms such as early age cracking cause …

Assessment of Infrared Thermography for NDE of FRP Bridge Decks
… that 238,357 (41%) of the nation's 577,710 bridges are either structurally deficient or functionally obsolete. New materials, such as fiber reinforced polymeric composites (FRP), are being suggested for use in bridge systems to solve some of the current problems. These materials are thought …

Dynamic response evaluation of fiber-reinforced composite bridge decks and bridges
Fiber Reinforced Polymer (FRP) composite bridge decks are gaining attention of bridge owners because of their light self weight, corrosion resistance and ease of installation. The lighter weight and lower stiffness of the FRP decks combined with the lower level of damping (than concrete) can lead …

Detection of subsurface anomalies in composite bridge decks using infrared thermography
… evaluation of subsurface anomalies in composite bridge decks.;Composite bridge deck specimens were constructed in the laboratory with varying subsurface delamination conditions such as sizes, thicknesses and filler materials. These simulated delaminations were placed between the 3/8&inches; thick …

Development Of A Simplified Finite Element Approach For Frp Bridge Decks.
Moveable bridges in Florida typically use open steel grid decks due to the weight limitations. However, these decks present rideability, environmental, and maintenance problems, for they are typically less skid resistant than a solid riding surface, create loud noises, and allow debris to fall …

An analytical field and model study of M-beam bridge decks
An analytical field and model study of M—beam bridge decks is presented. The field study involved testing four full size bridges during construction to establish the load distribution characteristics and included both tee beam and pseudo—box types of deck. After validating the grillage method of …
