The design of steel structures has evolved significantly over the decades, transitioning from the traditional Working Stress Method (WSM) to the modern, more robust Limit State Method (LSM). In contemporary structural engineering education and practice, especially within the context of Indian Standards (IS 800:2007), Dr. N. Subramanian’s textbook, Design of Steel Structures: Limit State Method , stands as one of the most comprehensive and sought-after resources.
Every design equation and steps align perfectly with IS 800:2007. It acts as an interpretive guide to the often complex codal provisions. Solved Examples
: High-strength friction grip (HSFG) bolts, bearing bolts, and joint efficiency.
