Unit 1
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.
Unit 2
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.
