Course

Unit 1

Introduction to different structural systems, load paths, loads on buildings, and serviceability requirement – Hands-on: Modelling of steel buildings using commercially available software – Introduction to fabrication, erection aspects and inspection of completed structure. – Introduction to structural steel sections, material property, geometric properties, classes of sections, stresses, residual temperature stresses in rolled steel sections, loads. Introduction to Tubular sections. Types of connections – 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 – concepts of net section including shear lag effects and block shear.

Unit 2

Plastic behaviour of structural steel – shape factor – plastic hinge concept – collapse load – methods of plastic analysis – plastic analysis of beams and portal frames. Analysis and design of laterally restrained & unrestrained simple & compound beams – Design for flexure, shear, bearing and check for serviceability criteria.

Unit 3

Design of axially loaded and eccentrically loaded compression members – built up columns and lacings. Industrial roofs – Introduction to steel roof systems – various elements – loads – wind load estimation for plane roof trusses. Hands-on: Analysis and Design of warehouse
