We will design the first exterior girder. Select Span 1 and Girder A. WSDOT girders have standard stirrup configurations. We don't want the PGSuper Designer to attempt to re-design these standard ...

The bridges will now be built using traditional steel girders, instead of fiber-reinforced polymer (FRP) composite girders.

Add Yahoo as a preferred source to see more of our stories on Google. When what is known as a "tub girder" began coming into use in highway construction in the 1960s and '70s, engineers thought a lot ...

For long spans, use of fewer but deeper girders to span the long distance between supports becomes more efficient. With appropriately spaced stringers between the main girders of highway bridges, ...

Past practice in design of new highways often located bridges first, then aligned the roadway with them. Current practice, in contrast, usually fits bridges into the desired highway alignment. Since ...

Engineering researchers at The University of Alabama are testing massive concrete girders in a campus laboratory to find ways for bridges to span longer distances with fewer supports underneath.

The purpose of the slab haunch is to provide a structural spacer between the bottom of the constant thickness slab and the top of the girder such that the roadway riding surface meets specified ...

Tokyo, Japan – Researchers from Tokyo Metropolitan University have carried out a detailed simulation showing how a common type of bridge fails during large-scale earthquakes. They modeled “I-shaped ...

When what is known as a “tub girder” began coming into use in highway construction in the 1960s and ‘70s, engineers thought a lot about design –– but never about the idea that people without homes ...
