Fracture Feature and Failure Cause Analysis of Cable Wire on Bridges

Abstract:

Cable wire is characterized by light weight and high strength and is widely applied in long span bridges. However, steel cable wire is vulnerable to fatigue and corrosion, which has been proved to be true through collapses of several bridges because of cable failure. This paper will the following 4 types of the fractures of steel wire: cone-shaped fracture, serrated fracture, cup-shaped fracture and step-like fracture to explore failure cause of cable wire. This paper also illustrates the fracture feature respectively and failure causes considering environmental and loading condition of cable.
