DK Ching VD - Cable Structure

cable structure

a structural system utilizing the cable as the principal means of support

cable

a flexible structural member, such as wire rope or metal chain, having high tensile strength but offering no resistance to compression or bending

sag

the vertical distance from the supports to the lowest point of a cable structure

funicular shape

the shape assumed by a freely deforming cable in direct response to the magnitude and location of external forces

funicular polygon

the shape assumed by a freely deforming cable in direct response to a set of concentrated loads

funicular curve

the shape assumed by a freely deforming cable in direct response to a uniformly distributed load

catenary

the curve assumed by a perfectly flexible, uniform cable suspended freely from two points not in the same vertical line

funicular structure

a structure shaped to carry or support a given loading by either axial tension or compression

lenticular structure

a lens-shaped structure having the outward thrusts of an arch balanced by the inward pulls of a cable, resulting in no net lateral forces at the supports

suspension structure

a structure of cables suspended and prestressed between compression members to directly support applied loads

suspension bridge

a bridge having a deck suspended from cables raised on towers and securely anchored to abutments at the ends

single-curvature structure

a suspension structure utilizing a parallel series of cables to support surface forming beams or plates

guy cable

a cable for absorbing the horizontal component of thrust in a suspension or cable-stayed structure and transferring the force to a ground foundation

mast

a vertical or inclined compression member in a suspension or cable-stayed structure, supporting the sum of the vertical force components in the primary and guy cables

double-cable structure

a suspension structure having upper and lower sets of cables of different curvatures

primary cable

one of the pretensioned cables directly supporting the load on a suspension structure

secondary cable

one of the pretensioned cables used for stabilizing a suspension structure against flutter, usually having a curvature opposite to that of the primary cables

double-curvature structure

a suspension structure composed of a field of crossed cables of different and often reverse curvatures

boundary cable

a cable for anchoring a set of secondary cables in a suspension structure

cable-stayed structure

a structure having vertical or inclined masts from which cables extend to support horizontally spanning members arranged in a parallel or radial pattern
