The module probes into the essential components that keep bridges functional. We'll explore how to calculate loads acting on box culverts. You'll gain a step-by-step understanding of designing single cell box culverts. Retaining structures will also be covered. We'll even explore innovative solutions like seismic isolation devices to safeguard bridges during earthquakes. From expansion joints that allow for thermal movement to crash barriers for safety, this module equips you with the knowledge to design a box culverts and.

Master the design of beam and slab bridge superstructures with this in-depth module! We'll guide you through a step-by-step process, from idealizing the bridge deck as a grillage system to analyzing and designing its components. You'll learn how to calculate effective section properties and apply loads accurately, considering impact factor and congestion factor. We'll delve into both ultimate and serviceability limit state design, ensuring the bridge can withstand various loads while functioning well. Transverse analysis techniques and special considerations for skewed or curved bridges will also be covered. By the end, you'll be equipped to confidently analyze and design beam and slab type bridge superstructures that are both safe and efficient.

Explore into the world of steel and steel composite bridges in this comprehensive module! We'll explore key standards like IRC 24 and dive right into different steel bridge types. You'll then be introduced to steel composite girders, which combine steel and concrete for enhanced performance. We'll cover the essentials of modelling these composite girders, followed by in-depth design considerations for flexure, shear, and fatigue. By the end, you'll possess the knowledge to design steel and steel composite superstructures that are both strong and efficient for a variety of bridge applications.
