Limit state design is a performance-based approach. It ensures that a structure remains fit for its intended use throughout its life. Unlike older methods that focused only on stress, LSD considers multiple failure criteria. 📍 Two Primary Limit States Ensures the structure does not collapse. Covers fracture, buckling, and overturning. Focuses on extreme loading conditions. Limit State of Serviceability: Ensures the structure is comfortable and functional. Includes limits on deflection (sagging). Controls vibrations and corrosion. Prevents unsightly cracking or swaying. 📖 Key Features of S.K. Duggal’s Approach

The Indian lifestyle is a unique blend of traditional and modern practices. While many Indians continue to live in rural areas and follow traditional ways of life, others have adopted modern urban lifestyles, with a focus on education, career, and personal growth. : Evaluation of net effective area and block shear

WSM does not account for the reserve strength of steel beyond the elastic limit. This often results in overly heavy, uneconomical structures. 2. Plastic Design Method
