A grid deck uses beams and diaphragms as the supporting structure. The supporting system of a grid deck is analyzed using a grillage analysis. A slab deck is one where the deck is analyzed as a plate. 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.
The deck of the bridge was an open grid design to decrease weight and ease lifting of the bridge to allow ship traffic to pass underneath. [37] The bridge used >400-short-ton (360-metric-ton) counterweights to lift the deck span portion to allow tall-masted vessels underneath. [38]
The original concrete deck of the 670 m (2,200 ft) North Viaduct of the Lions Gate Bridge was replaced with a lighter and wider orthotropic deck, carried out in sections using a series of short closures of the bridge. [3] Cantilever orthotropic decks allowed the Tamar Bridge to remain open whilst the main deck was replaced in 1999. An ambitious ...
The bridge consists of four steel through truss spans, each 70.71 metres (232.0 ft) in length, for a total length of 287.12 metres (942.0 ft), which carries a two lane open steel grid deck roadway. The bridge was constructed in 1920, replacing a cable ferry, and opened in 1921. Its original asphalt and timber deck was replaced with the current ...
Construction of the bridge began in fall 2018 and construction on the bridge deck began in December 2022, with the opening timeline delayed amid the COVID-19 pandemic. The bridge deck was ...
The stiffening truss is open to reduce wind resistance. The road deck is shaped as an airfoil to provide lift in a cross wind, and the center two lanes are open grid to allow vertical (upward) air flow, which fairly precisely cancels the lift, making the roadway stable in design in winds of up to 150 miles per hour (240 km/h).
Deck panels from the Tappan Zee Bridge are included in plans for a $4.8 million replacement of bridges carrying State Route 248 over Sugar Creek and Bennetts Creek in the Town of Canisteo in ...
The roadway deck through the cantilevered span was an open steel-grid deck, similar to that of the Castleton Bridge just south of Albany, New York, or the now-demolished Sikorsky Bridge on the Merritt Parkway in Connecticut. The deck proved to be extremely slippery when wet.
