Commonly Encountered Damages in Cable Members of CFST Arch Bridge and Detection Methods

Abstract

A thorough research was made on the commonly encountered damages in cable members of the concrete filled steel tubular (CFST) arch bridge and their detection methods. Four main types of damages, including cable protection measure damage, anchor system damage, cable body damage and other damage types were discovered after a comprehensive study of the cable members on some existing CFST arch bridges and the related references. A focus has been placed to analysis each types of damages individually, based on their characteristics, failure mechanism and destructive effects. Furthermore, the detection methods for the damages in cable members were introduced and evaluated elaborately. Therefore, this study provides a valuable reference for the daily maintenance and maintenance specification establish for cable members of CFST arch bridge under different scenarios.
