Fundamental Study on Damped Free Vibration Characteristics of Carbon Fiber Composite Cable

Abstract

Recently, a Carbon Fiber Composite Cable (it is hereafter called a CFCC) has been applied for cable-supported footbridges since it is lightweight, high strength and high-corrosion resistance. However, the weight saving of a cable also induces the vibration problem due to wind action and vehicle excitation. It is necessary to investigative the damping characteristics. In this paper, two kinds of experimental studies were conducted for the purpose of clarifying the damping performance of CFCC comparing with a steel wire.
