Syllabus

Introduction to Bridge Engineering

Delve into the world of bridge engineering in this introductory module! We'll explore the history of bridges, how they're classified by material, form, use, and more. We'll break down the key components that make up a bridge, from its main structure to its safety features. By the end, you'll have the ability to identify the different components and types of bridges.

Conceptual Design of Bridges

We'll delve into the intricate process of bringing a bridge from concept to reality. We'll explore the planning stages, analyzing factors like site characteristics, traffic flow, and environmental impact. Detailed investigations into soil conditions, water currents, and wind conditions ensure a safe and durable structure. Then, we'll dive into the design phase, considering bridge type, functionality, and even aesthetics. Finally, we'll cover the meticulous execution process, from construction planning to testing and commissioning. By the end of this module, you'll be able to explain the journey a bridge takes in the stage of planning.

Design Loads on Bridges

Dive into the world of bridge design by understanding the forces they have to withstand! The module explores various types of loads, from permanent loads to dynamic loads. We'll analyze how these loads are combined for design purposes, following IRC guidelines. You'll learn about specific loads for highway, railway, and pedestrian bridges, including construction phase considerations. Thermal effects, water current forces, and accidental impacts are factored in. By the end, you'll be equipped to design bridges that can handle the full spectrum of forces they'll encounter throughout their lifespan.

Structural Analysis

We'll delve into the calculations that ensure a bridge's strength. We'll explore various analysis methods, from traditional hand calculations like Pigeaud's method for slabs to advanced computer-aided tools like Finite Element Analysis (FEM). You'll learn about grillage analysis, which breaks down a bridge deck into a network of beams to understand load distribution. We'll also tackle examples using grillage analysis for different bridge configurations like slab bridges and slab & beam bridges. By the end, you'll possess a strong foundation for analyzing and designing bridges that can withstand various stresses and strains.
