Limit State Design Of Steel Structures By Sk Duggal |top| Jun 2026

S.K. Duggal's Limit State Design of Steel Structures focuses on ensuring safety and serviceability in compliance with IS 800:2007, utilizing partial safety factors for load and material resistance. Key principles include designing for both Ultimate Limit State (ULS) to prevent collapse and Serviceability Limit State (SLS) to maintain functionality. A summary of these methods is available on Scribd, and a comprehensive overview of the text is accessible via Google Books .

To transfer heavy column loads safely to the concrete foundation, Duggal explains the design of: Used for axially loaded columns. limit state design of steel structures by sk duggal

(Load Factors): Account for accidental overloads or structural analysis inaccuracies. γmgamma sub m Failure due to excessive deformation

Failure due to excessive plastic deformation, rupture, or fatigue. 2. Limit State of Serviceability

This state ensures the structure can withstand design loads without collapse, instability, or structural failure. It covers: Loss of equilibrium of the structure or its parts. Loss of stability against overturning or swaying. Failure due to excessive deformation, rupture, or buckling. Fracture caused by fatigue. 2. Limit State of Serviceability

Ensuring the structure retains its strength for a specified period during a fire event. Partial Safety Factors
