Optimization for suspender forces of tied arch bridges in non-falsework

ZHANG Guo-quan；XU Lei

Abstract: Yunzaobang Bridge is referred to calculation and construction of adjustment of tensioning force of suspenders. Calculations are achieved by establishing plane finite element models. Technology of adjustment and methods of adjustment using Bridge Doctor program are discussed to supply references to design and construction of tied arch bridges.

Keywords: tied arch bridge, suspender, adjustment, force matrix of tendons, target forces of tendons
