Course Aim: To impart sound knowledge on the behaviour and design of steel structures.

Intended Learning Outcomes:

On successful completion of the course, the students should be able to;

➢    explain properties of structural steel, section properties and the behaviour of steel structures.

➢    apply the limit state design principles for structural design.

➢    assess the loads and identify load paths in a structure.

➢    design members and connections of a steel structure conforming to a standard code of practice.

Course Content:

➢    Introduction to steel structures; Design concepts: Permissible stress, load factor, limit state

➢    Limit state concept: Probabilistic approach, characteristic loads, characteristic strength, and partial factors of safety

➢    Types of loads, their effects and load paths: Permanent and variable loads including imposed and wind loads, the static and dynamic nature, their effect on the structure

➢    Physical and mechanical properties of structural steel: Safety, serviceability, durability, fire resistance and other considerations of steel structures

➢    Behaviour of structural elements: Modes of failure, application of codes of practice, standards and specifications

➢    Design of tension members

➢    Design of Compression members

➢    Design of restrained and unrestrained beams

➢    Design of columns: Columns in simple construction and continues structures (rigid beam-column connection); Lateral stability of the steel frame buildings (includes bracing design for simple frame buildings considering lateral loads & geometric imperfections)

➢    Design of connections: Introduction to rigid and flexible connections, bolted and welded connections, Design of an extended end plate connection (rigid connection), Design of a partial end plate connection (simple connection), Design of base plate, Design of gusset plate

➢    Robustness of structures: Drafting of steel details

➢    Introduction to design software & drafting of steel details : 2 hrs session in Design Class for FE analysis
