Aug 03, 2017 · 13. Suspension Cable: It is used in suspension and cable-stayed bridges for the hanging, supporting and counter balancing of the bridge deck. Also Read – DIFFERENCE BETWEEN PRE-TENSIONING AND POST-TENSIONING. Nov 02, 2017 · The Suspension Bridge A suspension bridge is one where cables (or ropes or chains) are strung across the river (or whatever the obstacle happens to be) and the deck is suspended from these cables. Modern suspension bridges have two tall towers through which the cables are strung. Thus, the towers are supporting the majority of the roadway's weight. Wind tunnel tests of the roadway shape have eliminated that possibility for the Bosporus bridge, and Freeman Fox designers then added a further aerodynamic damping factor by drawing the normally vertical hanger cables at distinct angles to the vertical, the better to transmit horizontal forces to the main cables.
The nearly mile-long cable is also the longest looped suspension cable in any bridge. The cable features 118 miles of 2 1/2-inch steel strands and more than 17,000 5mm wires, each of which can support the weight of a military grade Hummer. The cable is comprised of 137 steel wire strands, each of which contains 127 steel wires.

parabolic shape, provided the dead load of the deck for a suspension bridge or a suspended girder will be uniformly distributed over the horizontal projected length of the cable. Hence, if the girder in Fig. 5—4a is supported by a series of hangers, which are close and uniformly spaced, the load in each hanger must be the same so as to ensure that the cable has a parabolic shape.

Suspension Bridge In a suspension bridge the shape of the suspension cables is parabolic. The bridge shown in the figure has towers that are 600 m apart, and the lowest point of the suspension cables is 150 m below the top of the towers. Find the equation of the parabolic part of the cables, placing the origin of the coordinate system at the vertex. SOLUTION: The cables of a suspension bridge are in the shape of a parabola. The towers supporting the cables are 500 feet apart and 60 feet high. If the cables touch the road surface midway. Algebra: Conic sections - ellipse, parabola, hyperbola. Section.

The bridge decks are suspended from the cable using the hangers. The stiffened deck prevents the supporting cable from changing its shape by distributing the live load moving over it, for a longer length of cable. In such cases cable is assumed to be uniformly loaded. Consider a cable which is uniformly loaded as shown in Fig 5.4.
