DESIGN OF STEEL STRUCTURAL ELEMENTS
COURSE OBJECTIVE
• To introduce the students to limit state design of
structural steel members subjectedto compressive, tensile and bending loads,
including connections and to provide the students the tools necessary for
designing structural systems such as rooftrusses and gantry girders as per
provisions of current code (IS 800 - 2007) of practice.
UNIT I
INTRODUCTION TO STRUCTURAL STEEL AND
DESIGN OF CONNECTIONS
9 General -Types of Steel -Properties of structural
steel - I.S. rolled sections - Concept of Limit State Design Design of Simple
and eccentric Bolted and welded connections - Types of failure and efficiency
of joint - prying action - Introduction to HSFG bolts
UNIT II
DESIGN OF TENSION AND COMPRESSION
MEMBERS
Behaviour and Design of simple and built-up members
subjected to tension - Shear lag effect- Design of lug angles - tension splice
- Behaviour of short and long columns - Euler's column theory- Design of simple
and built-up compression members with lacings and battens - Design of column
bases slab base and gusseted base
UNIT III
DESIGN OF BEAMS
Design of laterally supported and unsupported beams
- Design of built-up beams - Design of plate girders
UNIT IV
INDUSTRIAL STRUCTURES
Design of roof trusses - loads on trusses - purlin
design using angle and channel sections - truss design, Design of joints and
end bearings-Design of gantry girder - Introduction to pre-engineered buildings
UNIT V
PLASTIC ANALYSIS AND DESIGN
Introduction to plastic analysis - Theory of plastic
Analysis - Design of continuous beams and portal frames using plastic design
approach
TOTAL:
45 PERIODS
COURSE OUTCOMES:
Upon completion of this course, students will be
able to:
CO1
Recognize the design philosophy of steel structures and identify the different
failure modes of bolted and welded connections, and determine their design
strengths
CO2
Select the most suitable section shape and size for tension and compression
members and beams according to specific design criteria
CO3
Apply the principles, procedures and current code requirements to the analysis
and design of steel tension members, columns, column bases and beams
CO4
Identify and compute the design loads on Industrial structures, and gantry
girder
CO5
Find out ultimate load of steel beams and portal frames using plastic analysis
