The document discusses the design of steel structures using the limit state method. It provides references on the design of steel structures and Indian Standard codes related to loads on structures. The document outlines different types of steel structures like multi-story buildings and bridges. It also describes the properties, grades, loads, load combinations, sections and connections used in steel structures.

12. Steel Structures
• Strength approximately 10 times that of concrete.
• Large strength to weight ratio.
• More economical than concrete structures for high
rise structures
• Fast construction speed.
• Fast construction speed.
• Can be easily repaired and retrofitted to carry higher
load.
• Can be easily dismantle and sold as a scrap.
• Scrap value is more.

13. • Ductility.
steel can undergo large plastic deformation
before failure, thus providing a large reserve
