Grillage Analogy for Multigirder Bridges
Grillage analogy is a method frequently used to simulate the structural response of highway bridges with reinforced concrete deck and steel girders. This approach saves substantial efforts...

Dynamic Response of Bridges Under Traffic Loads
Numerous analytical and experimental investigations have been carried out in the past to study the complex dynamic problem of the response of a bridge deck to a moving vehicle. However,...

Combined Boundary Element and Finite Element Analysis of Composite Slab on Girder Bridges
In this paper, the coupling of boundary element and finite element methods and its application to analyze slab on girder bridges are studied. The boundary element method (BEM) is employed...

A Finite Difference Approach to the Modelling of Thick Bridge Decks
The finite difference method, although well known as an efficient numerical method, was applied in the past, in the case of slabs, only for the solution of thin slabs. In the present study,...

Highway Speed Radar for Pavement and Bridge Deck Evaluation
Radar has been developed as an economical alternative evaluating pavement layer properties and estimating quantities of deterioration in bridge decks. These highway applications are based...

Automated Generation of NBI Reporting Fields from Pontis BMS Database
Methods to generate National Bridge Inventory (NBI) condition ratings for deck (Field 58), superstructure(Field 59), substructure (Field 60) and culvert (Field 62) from the bridge database...

Closing the Loop
The 5.1 mi Cooper River Bridge, the longest in South Carolina, completes the I 526 Mark Clark Expressway around Charleston. It is a two-way, four-lane structure with the capability of...

Shear Connection in Composite Beams
This paper considers the influence of the shape of the deck profile on the shear connection of composite beams. It was found that the existing strength reduction factor can be unconservative...

Highlights of the New ASCE Standards on Composite Deck Floor Slabs
This paper presents highlights of the newly approved and printed ASCE Standard on the design and construction of composite floor deck slabs utilizing cold-formed steel. In 1992 four documents...

European Good Practice in Composite Floor Construction
Previous European experience, research and design for composite slabs with profiled steel decking are discussed. Present efforts to harmonize composite slab design and good construction...

Thermal Shielding in Continuous Span Composite Slabs
The increasing popularity in Europe of composite slabs with cold-formed steel decking has underscored the need to improve calculation rules for the fire resistance. Existing rules have...

The Steel Deck Institute Method for Composite Slab Design
The Steel Deck Institute (SDI) of the USA has synthesized the composite slab research and testing that has been conducted in the U.S. during the past 25 years and has presented a design...

Effects of Creep in Cable-Stayed Composite Bridges
The paper summarizes the various ways in which creep in the concrete slab may affect the stresses in a cable-stayed composite bridge. It explains one effect in particular which is not...

Strength and Stiffness Behavior of Composite Steel Grid Decks
This paper briefly discusses the historical development of composite steel grid decks. The static and fatigue behavior under bending of filled and unfilled steel grid decks (exodermic)...

Fatigue of a Steel Plate and Concrete Composite Bridge Deck by Moving Loads
This paper is devoted to reveal fatigue characteristics of a steel plate and concrete composite bridge deck, which is often called the Robinson slabs, subjected to vehicle loads. 16 model...

Influence on Steel Deck on Composite Beam Strength
Results of a recent study were described in which 7 push-out tests and 4 composite beam tests were conducted. The results were consistent with other recent studies reported in the literature,...

Composite Beams with Headed Studs in Narrow Ribbed Metal Deck
This paper presents the results of sixteen push-out tests conducted to study the behavior of headed stud connectors in composite beams with narrow ribbed metal deck placed parallel to...

Numerical Analysis of Composite Slab Behavior
A new calculation procedure is described which provides an alternative to full-scale testing for composite slabs with ribbed decking used in buildings. This procedure consists of combining...

Plastic Potential
Some 220,000 tons of epoxy-coated steel has been used in the construction of bridge decks since 1987, but some have raised questions about its long-term durability. New materials for prestressing...

Silica Fume Concrete: A Solution to Steel Reinforcement Corrosion in Concrete
This paper discusses the utilization of silica fume concrete admixture to prevent reinforcing steel corrosion. The mechanism of steel corrosion in salt impregnated concrete is described,...
