Course Handout Part II

Date: 03/08/2012

In addition to part -I (General Handout for all courses appended to the time table) this portion gives further specific

details regarding the course.

Course No. : CE C381

Course Title : Design of Steel Structures

Instructor-in-charge : MANOJ KUMAR

1. Scope and Objective of the Course

The course intends to impart design skills to common type of Civil Engineering Steel Structures as found in practice as

per revised code IS 800: 2007. An understanding of basic design concepts, loads and stresses to be used as per Indian

standards for steel design work will be developed. The course deals with designing of steel structural elements

subjected to axial tension, axial Compression, bending, combined twisting and bending. Moreover, emphasis will be

also given to the special structures such as beam-column, trusses, and plate girders. In addition, analysis and design of

various types of connections such as bolted and welded will be discussed for use in fabrication of tension,

compression, and flexural members in the framed structures. All design approaches will be based on Limit State of

strengths and serviceability. Furthermore, a special chapter on Plastic design of steel will also be introduced.
