Frequent short steps saddle pushing principle in suspension bridge construction;

Construction techniques on installation of cable saddle using simple hoisting equipments;

In this paper,the structural characteristics of the main cable system of the three-tower suspension bridge are analyzed and several applied technical issues in relation to the fabrication and installation process of the main cables,hangers,cable saddles and cable clamps of the bridge are studied as well.

In order to model the cable saddles in finite element analysis of suspension bridge more realistically and effectively,one class of new elements was developed.

Calculation of cable erection in suspension bridge with sliding saddles;

To model saddles in finite element analysis of suspension bridges,one class of new finite elements were developed,including two-node left-saddle element and right-saddle element that model a cable segment fixed with saddle at one end respectively,and three-node saddle element that models a cable segment fixed with saddle at one point on the cable.

This paper describes the self-designed and fabricated gantry lifting systems at the tower tops and anchorages, and the construction methods with the systems for lifting and installing of the tower saddles and splay saddles of the Suspension Bridge of Runyang Bridge.

By analyzing the conditions of equilibrium on the saddles while the wire strands are being erected, the theoretical calculation method of the pre displacement, which is the desired position of saddles, is developed.
