Multi-span additional bridging capability without cable length variations

Abstract

The performance of a multi-span cantilever bridge with no change in the length of a cable segment was studied using the bishops of Bangladesh Philly. First, a finite element simulation model for linear analysis is built. The accuracy of the finite element model is verified by comparing the measured data with the finite element analysis. Then, the effect of the cable-free section length and the middle span of the tower route on the horizontal displacement of the tower top, the vertical deflection of the middle span and the bending moment of the main beam are analyzed respectively.
