DEDICATION
This edition of theAISC Steel Construction Manual is dedicated to Robert O.Disque aretired AISC staff member and long-time member of theAISC Committee on Manuals.Bob or Mr. Steel as his friends on the Committee call him worked closely with the Committee on Manuals developing the Ist Edition of the LRFD Manual of Steel Construction and the9th Edition ASD Manual of Steel Construction.After retiring from AISC in 1991 Bobcontinued to be involved with the Committee as a member.

His career at AISC began as a District Engineer in Pittsburgh where he mar- He joined AISC in 1959 after working as a structural designer for firms in Philadelphiaketed to architects and engineers by providing them with the latest technical information onstructural steel. After a brief period as Assistant Chief Engineer he was promoted to ChiefEngineer in 1963 at AISC headquarters which at that time was in New York City. In thisAISC lecture series on steel design educating thousands of engineers across the country on capacity Bob supervised 32 engineers throughout the country. In 1964 he launched the firstvarious topics related to steel design and construction.
Engineering in Chicago where AISC made its home in the early 1980s. It was at this time the University of Maine only to return to AISC a few years later as Assistant Director ofthat he worked on the development of the two aforementioned AISC Mamuals. In 1991 Bobretired from AISC and joined the consulting firm of Gibble Norden Champion and Brownin Old Saybrook Connecticut.
Bob invented many things that today are the norm. He created the “snug tight” conceptfor bolted joints in conjunction with his contemporary and fellow Manual Committee mem-ber Ted Winneberger ofW&WSteel Company of Oklahoma City.He coined the term“anchor rods” to highlight that bolts are not rods; the astute reader will also note that itincorporates his initials. He advanced the use of flexible moment connections formerlybased on the beneficial inelastic behavior of steel.
Bob shared his knowledge of structural steel by authoring numerous papers and the textbook AppliedPlasticDesignofSteel.Healso co-authored the textbook Load andResistanceFactorDesign of Steel Structures with Louis F. Geschwindner and Reidar Bjorhovde.Of greatest importance to this Manual however Bob always emphasized that the Manual is not a text-book but rather a handbook to provide design guidance and aids for practicing engineers.
For all that he has done to advance the practice of structural steel design this Committee offriends and former colleagues is pleased to dedicate this 15th Edition Manual to Mr. Steel.
