Cable Tension Test Research of Short Boom

Abstract

For present-day bridges.cable tensions test is a vitally important job in course of construction.The tensions condition of cables plays an especially important part in the course of construnction and operation.In order to ensure the safety of operation and lengthen the service life,the exact testing result is being required to obtain.In cable stayed bridges and arch bridges, the boundary condition as well as the bending rigidity has an greater effect on the cable forces testing of the short boom.This paper based on Additional Mass Method,using the method of GA-BP Neural network after Genetic Algorithm optimization to identify the cable forces of short boom and a preferable research result is obtained.
