Abstract

In this paper, simplified formulas to determine the static behaviors of triple-tower suspension bridges were derived, including the formulas for the force of main cable, the deflection of the stiffening girder, the safety factor of anti-slipping on the saddle and the moment of the tower under the live load. Also, formulas were verified by a finite element model for three triple-tower suspension bridges with main span of 1500, 2000 and 2500 m. In the end, a parametric study was performed to investigate the influence of sag to span ratio, ratio of side span to main span as well as the stiffness of mid tower on the static performance using analytical method.
