Stability of Steel Framed Buildings

Stability of Steel Framed Buildings

Introduction

Frame stability concerns the significance of second-order effects and is highlighted as an essential check for all frames in BS 5950. Whilst in many braced frames the effects will not be significant, designers should be confident in using the simple checks to determine frame sensitivity, and the simple rules to allow for such effects.

This course explains the background, but focuses on practical application, with numerical worked examples at each stage.

Course Content:

• Second order effects in struts and frames
• The background and theory of frame stability
• The practical application of the BS 5950 rules to:
  • 1. braced frames
  • 2. continuous frames
  • 3. portal frames.
• The simple approaches in BS 5950 to allow for second order effects; amplified sway method or Appendix E.

David Brown

David Brown, BEng, MICE, graduated from the University of Bradford in 1982, and worked for several years for British Rail, Eastern Region, mainly involved with bridge design and installation in Braintree, Leeds and London. Latterly as technical director, his responsibilities included all tender and contract designs, all connection design and the drawing office activities.

After a brief period with J N Rowen, Mr Brown joined the Steel Construction Institute in 1992, with an interest in construction issues. This included the "Green Book" on moment connections, and various CIMsteel publications on manufacture and construction. He has also been responsible for a guide to the CDM regulations, advice on computer analysis, and the design of curved steel. He is a member of BSI and European technical committees. He manages the Standards activity at the SCI, including the development of a suite fo guides on Eurocode 3.

Mr Brown is now a deputy director at the Institute, but spends much of his time delivering technical courses, notably on Eurocode 3 , connections, frame design, BS 5950, and BS 6399-2.
