Structural Design of Steel work to EN 1993 and EN 1994 Third edition by L.H. Martin and J.A. Purkiss


This book conforms to the latest recommendations for the design of steel and composite steel–concrete structures as described in Eurocode 3: Design of steel structures and Eurocode 4: Design of composite steel concrete structures. References to relevant clauses of the Codes are given where appropriate. Note that for normal steelwork design, including joints, three sections of EN 1993 are required: 

• Part 1–1 General rules and rules for buildings.

• Part 1–5 Plated structural elements.

• Part 1–8 Design of joints.

Additionally if design for cold formed sections is carried out from first principles then Part 1–3 Cold formed thin gauge members and sheeting is also required. Whilst it has not been assumed that the reader has a knowledge of structural design, a knowledge of structural mechanics and stress analysis is a prerequisite. However, as noted below certain specialist areas of analysis have been covered in detail since the Codes do not provide the requisite information.

Thus the book contains detailed explanations of the principles underlying steelwork design and provides appropriate references and suggestions for further reading. The text should prove useful to students reading for engineering degrees at University, especially for design projects. It will also aid designers who require an introduction to the new Eurocodes. 

For those familiar with current practice, the major changes are:

 (1) There is need to refer to more than one part of the various codes with calculations generally becoming more extensive and complex. 

(2) Steelwork design stresses are increased as the gamma values on steel are taken as 1,0, and the strength of high yield reinforcement is 500 MPa albeit with a gamma factor of 1,15. 

(3) A deeper understanding of buckling phenomena is required as the Codes do not supply the relevant formulae. 

(4) Flexure and axial force interaction equations are more complex, thus increasing the calculations for column design. 

(5) The checking of webs for in-plane forces is more complex. 

(6) Although tension field theory (or its equivalent) may be used for plate girders, the calculations are simplified compared to earlier versions of the Code.

(7) Joints are required to be designed for both strength and stiffness. 

(8) More comprehensive information is given on thin-walled sections.


Lawrence Martin and John Purkiss would like to thank Long-yuan Li and Xiao-ting Chu for writing Chapter 11 on Cold-formed steel sections. The second author would like to thank Andrew Orton (Corus) for help with problems over limiting critical lengths for lateral–torsional buckling of rolled sections. The authors further wish to thank the following for permission to reproduce material: 

• Albion Sections Ltd for Fig. 11.1 

• for Figs 11.24 and 11.25 

• Karoly Zalka and the Institution of Civil Engineers for Fig. 8.13
