Limit State Design Of Steel Structures By Sk Duggal -

Introduction For decades, structural engineering relied on the "Working Stress Method" (WSM)—a philosophy that treated steel as if it should never break a sweat. This approach, while safe, was fundamentally inefficient and unrealistic. It ignored the ductile nature of steel and failed to predict how a structure actually behaves until collapse.

Duggal’s enduring lesson to the student is this: In doing so, you respect the ductility of steel, the probabilistic nature of nature, and the safety of the public. For anyone aiming to master IS 800:2007, S.K. Duggal remains the most helpful, clear, and philosophically sound guide available. limit state design of steel structures by sk duggal

In the Indian context, the shift from WSM to the , codified in IS 800:2007 , marked a revolution. No textbook has demystified this shift more effectively for Indian students and practitioners than S.K. Duggal’s Limit State Design of Steel Structures . Duggal’s work is not merely a collection of formulas; it is a philosophical guide that teaches engineers to think in terms of margins of safety rather than single factors of ignorance. Duggal’s enduring lesson to the student is this:
