For large-span structures where standard rolled sections fall short, the book provides complete structural breakdown for fabricated plate girders (including stiffener designs), gantry girders, and roof trusses. Core Highlights of Dr. S.K. Duggal's Textbook

The limit state design method has several advantages over traditional design methods, including: limit state design of steel structures by sk duggal pdf
A significant portion is dedicated to beams, explaining how to prevent lateral-torsional buckling and ensure the steel section is compact enough to develop its full plastic strength. Specialized Structures:
Limit state design is a method of designing structures to ensure that they can withstand various loads and stresses without failing. This approach considers the structure's behavior under different loading conditions, including ultimate loads, service loads, and fatigue loads. The primary objective of limit state design is to ensure that the structure remains safe and functional throughout its design life.
The traditional Working Stress Method assumes that steel behaves purely elastically under working loads. Structural safety is maintained by ensuring that the calculated stresses never exceed a fraction of the yield stress ( Key chapters focus on: For large-span structures where

If the compression flange of a beam is not laterally supported, it may buckle sideways and twist. The text details the design of both laterally supported and unsupported beams.
The textbook is structured logically, taking the reader from fundamental connections to complex structural assemblies. A. Connections (Bolted and Welded)
Before the widespread adoption of IS 800:2007, steel structures were primarily designed using the Working Stress Method (WSM). Dr. Duggal’s book highlights why the transition to the Limit State Method was a revolutionary step for structural engineering.
