Book excerpt: This book is primarily designed for the students of civil/structural engineering at all levels of studies--undergraduate and postgraduate degree as well as diploma--and also for the professionals in the field of structural steel design. It covers the fundamental concepts of steel design in the perspective of the limit state design concept as per IS 800: 2007, with the focus on cost-effective design of industrial structures, foot bridges, portal frames, and pre-engineered buildings. The connection design details are discussed concurrently with the design of members. The book covers the subject matter, with the help of numerous practical illustrations accompanied by step by step design calculations and detailing, in 14 chapters--including a chapter on pre-engineered buildings. Solved examples and chapter-end exercises are provided in each chapter to enable the development of strong understanding of the underlying concepts, as well as the testing of the comprehension acquired by the students. The geometrical properties of rolled steel sections, often required as per the revised clauses of IS 800: 2007 and not appearing in the existing steel tables, are given in the appendix for ready reference.
