Design Method of the Cable Saddle for CFRP Main Cable in Long-Span Suspension Bridge

Abstract:

Article Preview

A non-corrosion, high strength, light weight material – carbon fiber reinforced polymer (CFRP) is introduced to replace steel as cable system in long-span suspension bridge for improving loading efficiency, reducing maintenance cost, enlarging the span of suspension bridge. Because of the transverse weakness of CFRP, traditional cable saddle is not suitable. The contact forces between main cable and cable saddle slot under final state are investigated with a simplified analytical method. According to the mechanical characteristics of CFRP and the formulas deduced, the design suggestion of cable saddle for CFRP main cable of long-span suspension bridge are proposed.
