A tied-arch bridge is an arch bridge in which the outward-directed horizontal forces of the arch(es) are borne as tension by a chord tying the arch ends rather than by the ground or the bridge foundations. This strengthened chord may be the deck structure itself or consist of separate, independent tie-rods.
The Hernando de Soto Bridge is a tied-arch bridge carrying Interstate 40 across the Mississippi River between West Memphis, Arkansas, and Memphis, Tennessee.The design is a continuous cantilevered cable-stayed steel through arch, with bedstead endposts.
The inclined hangers with multiple intersections make the network arch bridge act like a truss, with only axial compressible and tensile forces. Bending moments and shear forces are very small in network arches. The hanger arrangement is what separates network tied arch structures from other types of tied arches, such as those with vertical ...
Cotter Bridge, a through arch bridge that has open spandrels. This type of bridge has an arch whose base is at or below the deck, but whose top rises above it, so the deck passes through the arch. The central part of the deck is supported by the arch via suspension cables or tie bars, as with a tied-arch bridge. The ends of the bridge may be ...
The bridge features twin tied-arch steel spans featuring two large blue ovals, augmented with additional ovals, meant to evoke images of footballs, to commemorate Super Bowl XL. [ 3 ] [ 4 ] The arches reach 70 feet (21 m) above I-94 and 87 feet (27 m) above US 24.
The Fremont Bridge is a steel tied-arch bridge over the Willamette River located in Portland, Oregon, United States. It carries Interstate 405 and US 30 traffic between downtown and North Portland where it intersects with Interstate 5 .
In a tied arch design, the horizontal thrust is resisted by longitudinal ties. In the five tied arches in Washington, the deck slab itself acts as a tie. This design eliminates the need of massive abutments to counter the horizontal thrust. This concrete, through tied, ribbed arch was constructed in 1934 by the West Coast Construction Company. [1]
