Course Learning Objectives: This course will enable students to understand the analysis and design of concrete bridges.

Note: All designs have to be done by Working Stress Method

Module -1

Introduction to bridges, classification, selection of bridge site and preliminary and detailed survey work
computation of discharge, linear waterway, economic span, afflux, scour depth. Design loads for bridges, introduction to I.R.C. loading standards, Load Distribution Theory, Bridge slabs, Effective width, Introduction to methods as per I.R.C.


Module -2

Design of Slab Bridges: Straight and skew slab bridges.


Module -3

Design of T beam bridges(up to three girder only) Proportioning of components, analysis of slab using IRC Class AA tracked vehicle, structural design of slab, analysis of cross girder for dead load & IRC Class AA tracked vehicle, structural design of cross girder, analysis of main girder using Courbon’s method, calculation of dead load BM and SF, calculation of live load B M & S F using IRC Class AA Tracked vehicle. Structural design of main girder.


Module -4

Other Bridges: Design of Box culvert (Single vent only). Design of Pipe culverts.


Module -5

Substructures - Design of Piers and abutments, Introduction to Bridge bearings, Hinges and Expansion joints.(No design). 

Course outcomes: After studying this course, students will be able to:

1. Understand the load distribution and IRC standards.
2. Design the slab and T beam bridges.
3. Design Box culvert, pipe culvert
4. Use bearings, hinges and expansion joints and
5. Design Piers and abutments.
