A cable-stayed bridge consists of one or more tall columns (Known as pylons or towers), with cables supporting the bridge deck.
In the cable-stayed bridge, the Pyłon is the primary vertical load-bearing structures. There are bearings provided at the pylon for vertical load carrying to support the deck at the pylon location, and the deck is suspended through stay cables, in which bearings are provided at the deck for vertical load carrying.
The nature of support in the Longitudinal and Transverse directions at pylons, abutments or piers is provided to suit design requirements. The stay cable bridges are constructed based on post-tensioning technology.
India has recently focused on the accelerated construction of a large number of special bridge structures like Cable Stayed Bridges, Extradosed Bridges, so the Indian Road Congress (IRC) felt the need to prepare separate documents for such bridges.
The IRC Committee takes the responsibility of preparing the document for Cable Stayed Bridges with technological input in 8-9 years before. This document for [IRC SP 136-2023] Cable Stayed Bridges was taken up to cover concepts, planning, aesthetics, design, analysis, wind and seismic effects, material, quality control, bearings, inspection, maintenance, structural health monitoring, etc. was undertaken by the Committee of IRC.
