Bending Fatigue Strength of Bridege Cable

Abstract

Bending fatigue strengths of various types of bridge cables were examined by full-sized fatigue tests. Tested specimens are following four types of full-sized cable systems including sockets; (1) CFRC type rope for hangers of suspension bridges and (2) locked coil rope, (3) parallel wire strand(PWS), (4) non-grouted type PWS with high fatigue-strength sockets for stay cables of cable stay bridges. Characteristics of stress behaviours due to the difference of cable structures were also analized.
