Abstract
The landscape of standards and codes for bridge design
is continuously evolving, with a surge in new guidelines
over recent years. To effectively incorporate these
standards, it is imperative to comprehend their
implications. Despite significant advancements in
structural design and modeling in recent times, there
remains ample room for improvement.
Various countries employ distinct highway bridge design
concepts and standards. In the context of Indian
highways, a multitude of bridges adhere to different
design criteria. Notably, many bridges are designed
according to the specifications of the Indian Road
Congress (IRC) and the American Association of State
Highway and Transportation Officials (AASHTO)
standards. The IRC has adopted both these standards for
highway and feeder road infrastructure. This thesis
undertakes an extensive review of renowned codes,
meticulously examining prevailing code requisites and
prevalent practices in bridge design acro
