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. : It moves away from the older Working
The design focuses on the laterals-torsional buckling of un-restrained beams, the effective length factor, and the bending moment reduction factor ($\alpha_LT$). Duggal’s examples highlight how LSM allows for higher utilization of steel’s plastic reserve compared to WSM. As S.K. Duggal meticulously explains
As S.K. Duggal meticulously explains, Limit State Design is a method that ensures a structure remains fit for its intended use throughout its lifetime. Unlike older methods that relied on a single "factor of safety" applied to the material strength, LSD uses for both loads and material strengths.
