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
