Limit State Design of Steel Structures by Duggal, S.K. - Amazon.ae

For each structural element, a step-by-step design procedure is provided, which is highly beneficial for students tackling design problems.

Before the adoption of IS 800:2007, the was the norm. Duggal’s book focuses on the transition to Limit State Design , which offers a more realistic and economical approach to engineering. The book categorizes Limit States into two main types: limit state design of steel structures by sk duggal pdf

The credibility of any textbook is deeply rooted in the authority of its author. Professor Shashikant K. Duggal brings immense academic and professional weight to his work. He is a long-standing professor in the Civil Engineering Department at the Motilal Nehru National Institute of Technology (MNNIT), Allahabad, bringing over 36 years of rich experience in teaching both undergraduate and postgraduate students. This extensive teaching background is a key reason for the book's clarity and student-friendly approach, as it is crafted by someone who intimately understands the learning process.

Design of components subjected to direct axial pulling forces. Duggal explains the concept of , accounting for staggered bolt holes, and addresses Block Shear Failure , a critical LSM criteria where a segment of steel literally tears out from the connection boundary. 4.

Material degradation, primarily corrosion in steel, which reduces the structural cross-section over time. Design of plate girders , gantry girders ,

Based on the McGraw Hill India syllabus, the text is structured to guide readers from basics to complex structural elements:

This book is primarily targeted at:

Design a simply supported I‑beam spanning 6 m, subjected to a uniformly distributed load of 20 kN/m and a point load of 30 kN at mid‑span. Steel grade: Fe 500 (fy = 250 MPa). Before the adoption of IS 800:2007, the was the norm

Fillet and butt welds, detailing the throat thickness, effective length, and stress distributions.

Understanding structural steel grades (such as E250 or E410), ductility, notch toughness, and weldability.

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:
