If the slab has a stiffness that is different in two directions (at right angles), then the deck is known and analyzed as an orthotropic deck. A beam and slab deck is one where the beams may deflect somewhat independently, and any transverse forces are carried in the deck. A cellular deck is one where a number of thin slabs and webs will ...
Beam bridges are the simplest structural forms for bridge spans supported by an abutment or pier at each end. [1] No moments are transferred throughout the support, hence their structural type is known as simply supported. The simplest beam bridge could be a log (see log bridge), a wood plank, or a stone slab (see clapper bridge) laid
Then, these components were combined in a Bayonne steelworks 5 mi (8 km) from the bridge site, and after the pieces of each slab were assembled, they were floated to the Narrows via barge. [101] Each piece measured 28 ft (8.5 m) high by approximately 115 ft (35 m) wide and long. These pieces of the deck were then hung from the suspender cables.
Kurilpa Bridge is the world's largest hybrid tensegrity bridge. [6] Only the horizontal spars conform to tensegrity principles. The Kurilpa Bridge is a multiple-mast, cable-stay structure based on principles of tensegrity producing a synergy between balanced tension and compression components to create a light structure which is incredibly strong.
Prefabricated bridge designs have been used in many bridge constructions to reduce the construction time. In the United States, there are efforts to come up with Prefabricated Bridge Elements and Systems in many states. Double tee structure is an alternative for short to medium spans between 40 and 90 feet (12 and 27 m).

These create standardized I-beam and wide flange beam [7] shapes up to 100 feet in length. A plate girder is a girder that has been fabricated by welding plates together to create the desired shape. The fabricator receives large plates of steel in the desired thickness, and then cuts the flanges and web from the plate in the desired length and ...
