The core technical section of the text is vast, covering the design of specific bridge components using Working Stress Method (WSM) and Limit State Method (LSM), depending on the edition and relevant codes (IRC codes).
The textbook is meticulously organized to take readers through the entire lifecycle of bridge construction. Key areas include: 1. Investigation and Planning
The Structural Engineering section of the Civil Engineering syllabus heavily tests concepts like influence line diagrams for moving loads, bending moments in bridge decks, and prestressed concrete design. Ponnuswamy provides step-by-step solved examples that perfectly match the analytical rigor required for GATE. 2. Indian Engineering Services (IES / ESE)
