AISC to Reprint Seismic Manual

October 02, 2006 From American Institute of Steel Construction, Inc.

Due to the discovery of a large number of errors in the First Printing (May 2006) of the Seismic Design Manual, AISC is temporarily withdrawing the book from circulation. "It's not unusual for subsequent printings of publications to include minor errata," explained Roger Ferch, AISC's president. "However, the errors discovered in this publication to date exceed our standards and we believe the entire Seismic Manual needs to be reviewed and revised." As a result of the review process, typesetting requirements, and printing schedule, the Seismic Manual is not expected to be available until April 2007. "We sincerely regret this problem and apologize for any inconvenience," Ferch added.

The errors are not in the online version of the Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341-05) or the Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications (ANSI/AISC 358), both of which are available as a free download on the AISC website at www.aisc.org/2005seismic.

The delayed publication of the Seismic Manual will not affect the AISC Seismic Provisions/Manual Seminar. "While I apologize that the Seismic Manual is not currently available, the information taught in the seminar is not dependent on attendees having the Seismic Manual," explained Louis F. Geschwindner, AISC's vice president of Engineering and Research. "However, all attendees will be given the 2005 Seismic Provisions and the 2005 AISC Moment Frame Prequalified Connection standard on CD."

In addition, everyone who previously purchased the Seismic Manual will be sent an apology and a CD with the 2005 Seismic Provisions and the 2005 AISC Moment Frame Prequalified Connection standard. They also will be sent a prepaid form to return the Seismic Manual. Purchasers will be given the option of either having the money refunded or of having a new Seismic Manual shipped to them in April.
