Assessment of Passive Fire Protection on Steel-Girder Bridges
<p>Bridges in the US are severely damaged or suffer collapse from fires at significant rates, even when compared to other hazards such as earthquakes. Fire-induced bridge collapses are perpetuated by the general lack of installed fire protection systems. Therefore, new materials and applications …

Elastic and ultimate behaviour of skew composite slab-on-steel girder bridges.
… skew composite concrete slab on compact steel girder bridges. Detailed parametric studies were conducted to find the effect of several parameters upon the load distribution characteristics in skew bridges at different stages of loading. In this work, both the nonlinear finite element …

Bridge maintenance to enhance corrosion resistance and performance of steel girder bridges
… on the condition of the various components. Bridges are fundamental elements of a highway system, representing an important investment and a strategic link that facilitates the transport of persons and goods. The cost to rehabilitate or replace a highway bridge represents an important …

Live load distribution factors for multi-span girder bridges with plank decking subjected to farm vehicles
… Load Distribution Factors (LLDFs) for highway bridges. The formulae for the AASHTO code-specified LLDFs have been developed, considering the effect of typical highway trucks. In addition to highway bridges, there are a large number of bridges located on secondary roadways where farm vehicles …

Testing and Analysis of a Fiber-Reinforced Polymer (FRP) Bridge Deck
… The structural performance of the FRP-on-steel-superstructure system was examined in the laboratory and field under service load. Tests results confirmed the following findings: (1) the clip-type of panel-to-stringer connection provides little composite action as expected, which fulfilled …

Evaluating the Effects of Shored Construction on Steel Girder Composite Bridges
<p>Steel composite girder bridges provide economic advantages and higher load-carrying capacity than non-composite alternatives. Over the years, a conventional sequence of un-shored construction for steel girder composite bridges has been developed. There is an alternative construction sequence, …

Assessment of Foundation Rocking Behavior in Reducing the Seismic Demand on Horizontally Curved Bridges
… to find ways to mitigate earthquake damage in bridges. One of the ways that has been proposed to achieve this is to permit the foundations to rock. In order to investigate the system effects of rocking foundations, a two-fifth scale, three-span horizontally curved steel plate girder bridge …

Lateral Load Distribution Factors for Military Vehicles on Multi-Girder Deck Slab Bridge Systems
… and shear forces for the design of highway bridges for civilian highway traffic. The maximum bending moments and shear forces caused by a wheel line load (or the entire vehicle) placed on the girders are multiplied by the distribution factors to calculate the design forces to include the …

The Viability of Steel-Concrete Composite Girder Bridges with Continuous Profiled Steel Deck
… short-span, simply supported composite steel girder bridges. However, because shear studs can only be welded to the girder through the steel deck at rib locations, the number of shear stud locations is limited to the number of ribs in the shear span while the spacing of the shear studs …

The Influence of the Recommended LRFD Guidelines for the Seismic Design of Highway Bridges on Virginia Bridges
… Guidelines for the seismic design of highway bridges in Virginia was investigated by analyzing two existing bridges. The first bridge has prestressed concrete girders and is located in the Richmond area. The second bridge has steel girders and is located in the Bristol area. The analysis …
