ENGINEERING TRIPOS PART IIB - 2012/2013

Module 4D10 - Structural Steelwork

AIMS

This module aims to bridge some of the gap between structural analysis, as taught in Parts I and IIA, and practical steel design as presented in design codes; however, although it will refer to the appropriate codes, it will not be an "introduction to the code" module.

LECTURE SYLLABUS

A separate handout with numerous worked examples covers each of the sections below.

Preliminary Details (1L)

• Steel properties and grading;
• Types of section;
• Principles of Limit-States design;
• Partial safety factors;
• British and European Standards.

Compact Member Design (4L)

• Flexural buckling of columns (axial loads) and effect of elastic restraints;
• Lateral torsional buckling of beams (transverse loads);
• Beam-column buckling using Column Deflection Curves and Interaction Equations.

Thin-walled Member Design (3L)

• Local buckling modes for a plate due to compression, bending and shearing;
• Definitions of compactness and effective sections for beams and columns;
• Panel performances in stiffened sections.

Joints and Composite Construction (4L,Mr Allan McRobie)

• Connections for simple and continuous construction;
• Bolted joints using bearing bolts and friction bolts;
• Welded joints using butt and fillet welds;
• Fatigue life of welds;
• Classification of weld joints;
• Detailing of joints;
• Composite section types;
• Composite section design using headed shear connectors;
• Composite floor slabs using profiled decking.

COURSEWORK

Design exercise for a simple two-storey office building, using methods from the course. Formal report for assessment.

OBJECTIVES

On completion of the module students should:

• Obtain an understanding of the background to the major codes of practice for structural steel work;
• Be able to apply these codes thoughtfully to the design of real steel structures;
• Be able to differentiate between the functions of compact, prefabricated sections and lightweight, thin-walled plate-girder members;
• Appreciate the vital function of joints and connnectors, and understand the limitation of various jointing techniques;
• Understand the performance of civil engineering composite structures.
