Steel in the News

Available Friday, July 1, this new burgundy publication (reminiscent of the 6th Edition Manual) contains, and is based on, ANSI/AISC 360-10, the 2010 AISC Specification for Structural Steel Buildings. Located in Part 16 of the Manual, the Specification is the standard that is referenced by building codes and job specifications. This document is the heart and soul of the information and recommendations provided in all the rest of the Manual, even though it may seem relegated to one of the last chapters.
AISC is aware of the difficulty experienced by the structural engineering profession when dealing with frequent changes in building codes and material standards. For this reason, the revisions made in this version of the Manual were limited to clarifications and a minimal number of technical changes. The Manual includes the following notable updates and revisions:
- All tabular information and discussions have been updated to comply with the 2010 Specification for Structural Steel Buildings, and the standards and other documents referenced therein.
- Shape information has been updated to ASTM A6-09, including the addition of two new shape series, HP18 and HP16.
- Weights of HSS are revised based on industry practice.
- The minimum Sz value for single angles is published based on the heel and toes of the angles.
- Tables for eccentrically loaded single angles are revised to be consistent with the Specification using the unsymmetric shape equations in Specification Section H2.
- Available compressive strength tables for filled HSS now indicate at what length the bare steel member controls the strength.
- The coefficients, C, in the eccentrically loaded weld group tables have been revised for the a=0 case (no eccentricity) to be consistent with Specification Chapter J. Additionally, the tables are supplemented to provide the strength for L-shaped welds loaded from either side.
- The procedure for the design of conventional single-plate shear connections is revised to accommodate the increased bolt shear strengths of the 2010 Specification for Structural Steel Buildings.
- Information is provided to determine if stiffening plates (stabilizers) are required for extended single-plate shear connections.
- The bracket plate design procedure is revised.
A full day seminar on the new Specification and Manual will kick off in mid-September and will be presented in cities throughout the United States. This will be the inaugural Louis F. Geschwindner Seminar Series entitled, Leverage Your Knowledge With the 2010 AISC Specification and the 14th Edition Steel Construction Manual. The important changes and clarifications that have been incorporated into the 2010 AISC Specification and the 14th Edition Steel Construction Manual will be explained in this seminar, including design examples illustrating the provisions and use of these publications. The new annual seminar series has been named to honor AISC’s immediate past Vice President of Engineering and Research, and to emphasize the importance AISC places on providing valuable continuing education programs to the steel design and construction community.
The Manual will be available for purchase on the AISC website at www.aisc.org/store for $175 (members) and $350 (nonmembers). The accompanying Version 14.0 database and design examples will be provided on the AISC website later this summer at www.aisc.org/shapesdatabase and www.aisc.org/designexamples.
