  Design of Steel Structures-I Learning Schedule
Pre-requisites: Structural Analysis 3 1 0 4


Study of BIS Codes i.e. IS:800-1984, IS:800-2007 related to design of steel structures. Study of design of different types of connections, simple and built up beams, laterally supported and unsupported beams. The subject imparts knowledge of design beams and columns under combined stresses. Design simple and built up beams and columns.


  1. To teach students loading and load combinations for the design of steel structures.
  2. To make the students familiar with the concepts of steel design starting with riveted, welded and bolted connections and eccentric connections based on IS:800-1984 and IS:800-2007.
  3. To teach the students design of tension, compression members and flexural members based on IS: 800-2007.
  4. To teach students beam-column design as a whole for uniaxial and biaxial loading along with elastic theory of buckling of beams and columns.


On completion of this course, the student will be able to

  1. Calculate load required on structure for the design of steel structure members.
  2. Design different type of joints and connections.
  3. Design of tension, compression and flexural members of the steel structures.
  4. Design beam-columns as a whole for different steel structural frame.
