Review of the Main Cable Shape Control of the Suspension Bridge
Pingming Huang, Chongjin Li
Abstract
The main cable shape control confronts new challenges when a suspension bridge’s span exceeds two kilometers. As a suspension bridge’s primary load-bearing component, it is difficult to alter the alignment once the erection is completed. Hence, the accurate calculation and control of the main cable shape has significant scientific research value from various aspects. This paper systematically reviews the research progress of the suspension bridge’s main cable shape control technology. The current research progress is introduced from three aspects of main cable shape-finding, construction control technology, and control analysis, and both the current shortcomings and future research directions are summarized. This review paper is expected to be a solid reference for investigators and experts in this crucial field of structural engineering.
