The preliminary design and technical-economic efficiency of the two-level branched cable-stayed bridge

Abstract

An innovative steel cable-stayed pedestrian bridge structure and the preliminary design methodology are provided in this article. The advantages and disadvantages of the bridge design are presented. The comparative analysis of the innovative steel cable-stayed pedestrian bridge structure and a similar structure of a single pylon fan cable-stayed bridge with an 80 m span is provided, the main criteria are reviewed and conclusions are formulated. The main features of the innovative branched cable-stayed bridge behaviour are reviewed. An overview of technical-economic efficiency and conclusions are presented.
