Course Outline:

🟢 Day 1: Fundamentals of Bridge Engineering

🔹 Introduction to bridge types: beam, arch, truss, cable-stayed, suspension.
🔹 Structural components of bridges: deck, piers, abutments, bearings, foundations.
🔹 Design codes and standards: AASHTO, Eurocodes, IRC, BS, ASTM.
🔹 Load considerations: dead load, live load, wind load, seismic load.
🔹 Case study: Analyzing a major bridge failure and lessons learned.

🟢 Day 2: Structural Design of Bridges

🔹 Reinforced and prestressed concrete bridge design.
🔹 Steel bridge design: plate girders, composite structures.
🔹 Bearing and expansion joint selection.
🔹 Load rating and safety factors.
🔹 Software session: Bridge design using MIDAS Civil, SAP2000, or STAAD.Pro.
🔹 Case study: Designing a reinforced concrete bridge for a highway.

🟢 Day 3: Culvert Design and Hydraulic Considerations

🔹 Types of culverts: box, pipe, arch, slab, and open channel culverts.
🔹 Hydrological analysis for drainage capacity.
🔹 Scour protection and erosion control measures.
🔹 Structural considerations for high-load and flood-prone areas.
🔹 Software session: Hydraulic modeling using HEC-RAS or HY-8.
🔹 Case study: Designing a culvert system for a flood-prone road section.

🟢 Day 4: Seismic, Wind, and Extreme Weather Considerations

🔹 Seismic design principles for bridges.
