Limit State Design of Steel Structures: An Analysis of S.K. Duggal’s Approach

7. Industrial Structures

SK Duggal's book, "Limit State Design of Steel Structures," is a comprehensive resource that provides a detailed treatment of the subject. The book covers the fundamental principles of limit state design, including the basic concepts of steel structure design, material properties, and structural analysis.

Significance of the Book

Specialized Content

: Unlike many general texts, it features dedicated sections on industrial structures such as tubular roof trusses , steel bridges, and light-gauge steel structures.

Design strength = (Critical moment) / γ 0

• Buckling classes (a, b, c, d) as per IS 800.
• Effective length factors for various end conditions.
• Built-up columns (lacing and battening) – a topic that confuses many students, yet he simplifies it using comparative tables of shear forces.
• Column bases: Slab base, gusseted base, and moment-resistant base plates.

Tutorial Approach

: Uses a step-by-step problem-solving methodology with numerous worked-out examples.
