Limit State Design Of Steel Structures By Sk Duggal «A-Z Best»

The core philosophy of limit state design, as articulated by Duggal, focuses on the "limit states" beyond which a structure no longer fulfills its intended function. These are divided into two primary categories: the limit state of strength (addressing safety and load-carrying capacity) and the limit state of serviceability (addressing deflection, vibration, and durability). By using partial safety factors for both loads and material strengths, the method provides a more consistent and reliable level of safety throughout the lifespan of the steel structure.

The text then tackles the design of individual structural members. Tension members, compression members, and beams are covered with extensive theoretical background followed by step-by-step design procedures. Duggal provides numerous solved examples that mirror real-world engineering problems, helping readers bridge the gap between classroom theory and site application. Special attention is given to the design of plate girders and gantry girders, which are vital components in industrial warehouses and heavy manufacturing facilities.

For students preparing for competitive exams like GATE, IES, or UPSC Engineering Services, this book is an indispensable resource. The practice problems at the end of each chapter are graded by difficulty, allowing for progressive learning. Furthermore, the detailed illustrations and tables derived from the IS 800:2007 code make it a handy reference for designers working in consultancy firms.
