Limit State Design of Steel Structures by SK Duggal: A Comprehensive Review and Guide
code, which transitioned Indian structural engineering from the older Working Stress Method (WSM) to the more modern Limit State Method (LSM) The Shift to Limit State Design The core philosophy of Duggal’s text revolves around the Limit State Method
Design of high-strength friction grip (HSFG) and bearing-type bolts under axial and eccentric loading.
This design philosophy is a modern, more rational approach compared to the older working stress method (WSM). Its core principle is to ensure a structure is both safe and serviceable throughout its lifespan by considering various "limit states". The two primary categories are:
The book is one of the most widely used textbooks for civil and structural engineering students in India and neighboring regions. It provides a comprehensive explanation of structural steel design based on the limit state method, aligned with the Indian Standard code IS 800:2007 . limit state design of steel structures by sk duggal pdf
The book is structured into roughly 18 chapters that move from fundamental principles to advanced industrial applications:
