These relate to the maximum load-carrying capacity. According to Duggal, a structure must not collapse or become unsafe under any combination of design loads. Key sub-categories include:

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.

Limit State Design of Steel Structures by S.K. Duggal is a widely recognized textbook used by engineering students and practicing professionals to master structural steel design using the code . The book focuses on the "Limit State Method" (LSM), which ensures structures are safe against collapse (Ultimate Limit States) and suitable for daily use (Serviceability Limit States).
