DEVELOPMENT LENGTH FOR SINGLE WIRE IN SUSPENSION BRIDGE CABLE

Development length is the length that a wire within a suspension bridge cable, should it break, will carry its full share of the cable force. The actual development length in a given situation depends on a number of uncertainties such as the packing pattern of the wire, the initial clamping or wrapping force, the distribution of contact forces between the wires, and the value of the coefficient of friction. The paper shows that this length depends on the tightness of the cable wrapping or clamping bands, but that this dependence is not very strong. If there is tightness in the cable, the development length is quite small. Very high contact stresses will develop between the broken wire and its neighbors due to Poisson's ratio.
