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 ...

The Grist Mill Bridge, a 75-ft single-span bridge in Hampden, Maine, is the first in the nation to use composite tub girders with no concrete reinforcement in the superstructure, say officials. The ...

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 top slab between the webs of a box girder and the cantilever plate is commonly called the bridge deck. A reasonable design of bridge decks is a concern of many bridge researchers and designers.

Prestressed concrete (PSC) box girder bridges curved in alignment are one of the most widespread and popular categories of highway bridges. The use of prestress enables the achievement of extended ...

A horizontally curved, precast- concrete, trapezoidal type of box-girder design that shaved some $9 million off an interchange project in Orlando, Fla., is attracting growing interest from the bridge ...
