Introduction to structural steel sections, material property, geometric properties, classes of sections, stresses, residual temperature stresses in rolled steel sections, loads. Types of design - rigid, semi rigid. Limit state design method – basic concepts, partial safety factors, load combinations, deflection limitations as per IS:800.
Analysis and design of bolted and welded connections to resist direct force and moment.
Design of tension members - single and double angle ties.
Plastic behaviour of structural steel – shape factor – plastic hinge concept – collapse load – methods of plastic analysis – plastic design of beams and portal frames. Local buckling of plates – stiffened edges.
Compression members: Axially and eccentrically loaded compression members - built up columns - lacings and battens - design of column bases.
Analysis and design of laterally restrained & unrestrained simple & compound beams - Design for flexure, shear, deflection, and bearing.
Industrial roofs: Introduction to steel roof systems - various elements - loads - wind analysis – design of plane roof trusses – design of roofing elements and purlins – wind bracings - Gusset connections.
Introduction to cold-formed steel structures (Light gauge steel sections).
