"Bridge Engineering" is not merely a theoretical textbook; it is a practical guide that covers the entire lifecycle of a bridge, from the initial investigation to design, construction, and long-term maintenance. Several key features distinguish this book:

Smooth or corrugated pipes used for minor drainage. Slab and Girder Bridges

: Calculating the required opening to prevent flooding and scouring. 2. Design Loads and Stresses Ponnuswamy that complement the book's topics

Design parameters for both post-tensioned and pre-tensioned concrete girders, as well as structural steel I-beams.

Moving vehicles, pedestrians, and trains. Standard configurations like IRC Class AA, Class A, and Class 70R loading are analyzed.

: Deep foundation systems, such as well foundations (caissons) or pile foundations, designed to bypass weak upper soil strata. 3. Core Engineering & Design Principles Several key features distinguish this book: Smooth or

Bridges are vital links in transportation networks, connecting communities and facilitating economic growth. S. Ponnuswamy introduces the subject by tracing the evolution of bridges from primitive log and vine structures to modern long-span mega-structures.

The components that directly receive and carry moving traffic. This includes the deck slab, wearing course, longitudinal girders, cross beams, and handrails.
