Analysis of the Influence of the Main Cable's Manufacturing Error on the Mechanical Properties of a Spatial Self-anchored Cable-net Suspension Bridge

Abstract

The Xinghai Bay Bridge in Dalian is a self-anchored cable-net suspension bridge with a spatial net and a multi-transferred cable system, which is the most notable feature that differentiates it from normal self-anchored suspension bridges. The question that is addressed is, as the main component of the bridge, what kind of influence of will the main cable's manufacturing error have on the mechanical properties of the system? To answer this question, and with reference to the results of a specific experimental model, this paper describes the detailed analysis of the cable-net system using a non-linear FE model. The conclusion that is drawn is that the longer the length of cable 1, the larger the stiffness of the structure; while the shorter the length of cable 2, the smaller the stiffness of the structure.
