Book Summary — Limit State Design of Steel Structures by S.K. Duggal
Author: S.K. Duggal
Focus: Practical introduction to limit state design (LSD) methods for steel structures, aligned with modern codes and suitable for students and practicing engineers.
The limit state design approach has several advantages over traditional working stress design (WSD) methods, including:
Limitations of the Book (A Balanced Critique)
No text is perfect. While SK Duggal excels in routine design, it has minor weak spots: limit state design of steel structures by sk duggal
Core Principles of Limit State Design in Duggal’s Framework
S.K. Duggal structures his text around two primary categories of limit states:
Design of Tension Members
Partial safety factors ((\phi)) are used in limit state design to account for uncertainties in material properties, fabrication, and loading. The values of (\phi) vary depending on the type of load, material, and fabrication process.
Concise takeaway A practical, example-rich textbook that teaches the principles and procedures of limit state design for steel structures with direct application to code-based engineering practice, especially within the Indian standards framework.

Recommendations
- Improved Safety: LSD provides a more consistent and reliable safety margin.
- Economy: LSD allows for more efficient use of materials, leading to cost savings.
- Simplified Design: LSD simplifies the design process by using a single set of design equations.
