Design and Analysis of Hybrid Cable-Stayed Bridges: A Comprehensive Study

This research paper aims to explore the design, analysis, and anticipated performance of hybrid cable-stayed bridges, with a specific focus on the Krishna River Bridge. Hybrid cable-stayed bridges offer structural advantage derived from unique combination of cable stayed and suspension structural arrangements leading to improved load-carrying capacity, structural efficiency, better foundation strata due to pylons placed nearer to the river banks, cost-effectiveness, and aesthetic appeal.

The paper will present a comprehensive study into various aspects involved in the analysis and design of hybrid cable-stayed bridges, with a particular emphasis on Krishna River Bridge Project on NH-167K in the States of Telangana & Andhra Pradesh in India. This will include examining the optimal structural configuration, cable arrangement and material selection for the bridge under different loading conditions. By conducting thorough analyses and simulations, this case study indicates that engineers and the client can make informed decisions during the design and construction phases of a bridge ensuring its safety, durability, functionality and cost effectiveness while achieving high aesthetic value making the structure an Iconic structure very well suited to the terrain and topographical features of the landscape at the Bridge site.
