STEEL CONSTRUCTION:

ECONOMIC & COMMERCIAL FACTORS

Lecture 1A.1: Introduction to Steel's Role in Construction in Europe

OBJECTIVE/SCOPE:

To inspire students with an enthusiasm for steel construction. To identify the advantages of steel for construction in Europe, emphasising its future potential and the rewarding challenge it offers to able students. To introduce ESDEP as a response to this potential.

SUMMARY

Steel has been produced for about 100 years. It is a modern material with an exciting future.

The advantages of steel are described together with recent developments which have enhanced them, i.e. improvements in manufacture, enhanced range of properties, improvements in fabrication and speed of construction, adaptability, consistent quality, lightness, stiffness and strength.

The future development of uses of steel, the associated training needs and the role of ESDEP in meeting those needs are discussed.

1. INTRODUCTION

Steel was first produced in the Middle Ages, but it was not until just over a century ago that it was used for structural engineering.

Today, many remarkable structures demonstrate the possibilities of this well developed material in their clear and transparent appearance, Slides 1 - 5.

• Steel is a modern material, produced in large quantity with high and reliable quality.

• Steel is available in a wide range of hot and cold rolled products, as plates and profiles.

• Steel is easily manufactured into end products. • Most of this manufacture takes place in quality controlled workshops. • Site connections can easily be made and can carry load immediately. • Given good corrosion protection and maintenance, steel has an indefinite

life. • Erection on site can take place quickly with little risk of delay. • Steel structures are light and strong and only require simple foundations.

• Existing steel structures can easily be adapted to new demands. • Quality Control and Quality Assurance will give a further guarantee of the

economic application of steel structures.

INTRODUCTION TO DESIGN

Lecture 1B.4.1: Historical Development of Iron and Steel in Structures

OBJECTIVE/SCOPE

To appreciate how steel became the dominant structural material that it is today, it is essential to understand how it relates to cast iron and to wrought iron, both in its properties and in the way that all three materials evolved.

PREREQUISITES

None.

Lecture 1A.2: Steelmaking and Steel Products

SUMMARY

The properties of the three ferrous metals, cast iron, wrought iron, and steel, are described and the evolution of their production is summarized. The evolution of their structural use is also given and the prospects for further development introduced.

• Up to the late 18th Century, structures were designed essentially on the basis of proportion.

• Intuition gave way to calculation for all materials and theory took over to an increasing extent in the 19th century.

• Much of the present practice in steel design derived originally from timber in the 19th century. At that time the understanding of cast iron and wrought iron grew largely on the basis of component testing and proof loading. Rigorous definitions of stress, strain, working stress, proof loading and factor of safety appeared in the mid 19th century and gradually ordinary engineers learnt to calculate simple structural forms on the basis of assumed elastic behaviour and believe in the calculations without testing.

• In the 20th century, the greatest advances in the theoretical understanding of structures were associated with the airship and aircraft industries.

• The introduction of welding in he 1930s and the development of the theory of plasticity led to major changes in design thinking.

• For the future, the wider use of computers offers the possibility of achieving greater efficiencies in structures by considering 'whole structure' behaviour including the effects of cladding and partitions.
