Numerical Model for Predicting Carbon Fiber Composite Cable Forces in a Cable-stayed Bridge

Abstract

Carbon Fiber Composite Cables (CFCC) have high tensile strength, low weight and excellent corrosion resistance. As such they provide a viable replacement to traditional steel cables in many cable-stayed bridges, which may increase the structure lifespan and reduce maintenance requirements. The Penobscot Narrows Cable-Stayed Bridge offered a unique opportunity to develop these technologies. This paper analyzes continuous CFCC structural health monitoring data, and investigates the relationship between the external ambient air temperature and CFCC forces via a numerical model
