Rules of Thumb for steel design

In earlier times when computers were neither available nor essential, one objective of the structural design process was to discover a computational method, which was elegant, simple and appropriately accurate. When such a process was identified it was recorded as an expedient approach to solving a recurring structural design problem.  Thus, quick “Rules of Thumb” became essential resources for the structural engineer.

As computer software has proliferated, has become very comprehensive, and has been made very user friendly, the importance of rules of thumb and approximate methods has been diminished.  It has been argued that, with the computational speed and ease of application of computer methods, the need for approximations and “Rules of Thumb” no longer exists.  However, equally imposing arguments can be made for the value of these quick approaches such as:

  • The structural engineer should have tools to make on-the-spot intelligent decisions,
  • A reasonable solution is often required as computer input,
  • The validity of the computer output should be verified with rational approximations.

So, with the objective of fostering continued development, use and enthusiasm for “Rules of Thumb” and approximate methods, several steel framing “Rules of Thumb” will be provided in this presentation.  Because a majority of these have been developed over the past they are based on Allowable Stress Design (ASD)  and are in imperial units.

Dr. Socrates Ionnides

Since founding Structural Affiliates International, Inc. (SAI) in 1986, Dr. Ioannides has planned and designed various types of structures including health care facilities, industrial facilities, commercial office buildings, hotels, parking garages, and high-rise structures. He holds licenses in 35 states, and he has designed buildings with a total construction value of over 3 billion dollars.

He has educated and managed personnel in Malaysia and Panama to design and implement structural steel into high-rise construction projects. He has also designed Torre Planetarium - 90 and 80 story towers in Panama City when completed. Currently, his design of the first major "steel high" rise project in Cyprus is under construction.

He has served on a variety of national and international committees and forums, and he has published dozens of papers on highly analytical, as well as practical, aspects of structural engineering.

Several of his designs have been recognized nationally and internationally. The first all-Malaysian steel high rise in Kuala Lumpur, MY, has received the “Outstanding Engineering Achievement” award from the Institute of Engineers of Malaysia (IEM).
