Object-Oriented Computer-Aided Analysis for Construction Control of Anchored Suspension Bridge

Abstract

With the increase of the span of suspension bridge, the weight of the main cable increases, and the safety margin becomes smaller. Thus high accuracy is necessary for the construction control analysis of suspension bridges. The traditional finite element software cannot meet the accuracy requirement because of temperature, cable saddle and other factors, which influence the construction control. Based on the modified segmental catenary method, this paper has come up with a fine analysis method for the construction control of suspension bridges. And a software program called ZambisSC has been developed using object-oriented programming language combined with a number of the latest software development technologies. Compared with the monitoring results of Nancha suspension bridge in Guangzhou, China, it shows that ZambisSC can predict the main cable shape with high accuracy.
