CE6013 BRIDGE STRUCTURES LT P C 3 0 0 3
OBJECTIVES:
• To make the student to know about various bridge structures, selection of appropriate bridge structures and design it for given site conditions.
UNIT I INTRODUCTION 9
History of Bridges - Components of a Bridge and its definitions- Classification of Road Bridges - Selection of Site and Initial Decision Process - Survey and Alignment; Geotechnical Investigations and Interpretations. River Bridge: Selection of Bridge site and planning - Collection of Bridge design data - Hydrological calculation
Road Bridges - IRC codes - Standard Loading for Bridge Design - Influence lines for statically determinate structures - I.L. for statically indeterminate structures - Transverse distribution of Live loads among deck longitudinal - Load combinations for different working state and limit state designs
Railway Bridges: Loadings for Railway Bridges; Railroad data. Pre-design considerations; - Railroad vs. Highway bridges.
UNIT II SUPERSTRUCTURES 9
Selection of main bridge parameters, design methodologies -Choices of superstructure types; Orthotropic plate theory, load + techniques - Grillage analysis - Finite element analysis - Different types of superstructure (RCC and PSC); Longitudinal Analysis of Bridge.- Transverse Analysis of Bridge- Temperature Analysis-Distortional Analysis-Effects of Differential settlement of supports- Reinforced earth structures
UNIT III DESIGN OF STEEL BRIDGES 9
Design of Truss Bridges – Design of Plate girder bridges.
UNIT IV DESIGN OF RC AND PSC BRIDGES 9
Design of slab bridges – Girder bridges – PSC bridges
UNIT V SUBSTRUCTURE, BEARINGS AND DECK JOINTS, PARAPETS AND
RAILINGS 9
Substructure - Pier; Abutment - Wing walls- Importance of Soil-Structure Interaction - Types of foundations - Open foundation- Pile foundation- Well foundation- Simply supported bridge- Continuous Bridge - Bearings and Deck Joints - Different types of bridge bearings and expansion joints - Parapets and Railings for Highway Bridges
TOTAL: 45 PERIODS
OUTCOMES:
• To develop an understanding of an appreciation for basic concepts in proportioning and design of bridges in terms of aesthetics, geographical location and functionality.
• To help the student develop an intuitive feeling about the sizing of bridge elements, ie., develop a clear understanding of conceptual design
• To understand the load flow mechanism and identify loads on bridges.
• To carry out a design of bridge starting from conceptual design, selecting suitable bridge, geometry to sizing of its elements.
