Seismic Design Manual
The 2nd Edition Seismic Design Manual includes sections on general seismic design considerations, analysis considerations, and systems not specifically detailed for seismic resistance. Different seismic force resisting systems are covered in the balance of the sections, along with diaphragms, chord and collectors as well as an introduction to engineered damping systems.
The Seismic Design Manual includes hundreds of pages of comprehensive design examples, including connections, updated for the 2010 AISC Seismic Provisions. Examples are shown with LRFD and ASD design methodologies side-by-side.
Also included are two AISC seismic-related standards: the 2010 AISC Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341-10) and the 2010 AISC Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications with Supplement No. 1 (ANSI/AISC 358-10 and ANSI/AISC 358s1-11).
- 2010 Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341-10), Third Printing
Generally referred to as just "the seismic provisions," this document covers the design of structural steel for seismic applications. This free downloadable version incorporates errata through the first printing of the 2nd edition Seismic Design Manual (September 2012). Learn more about the 2010 Seismic Provisions here.
- 2010 Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications with 2011 Supp. No. 1 (ANSI/AISC 358-10 with ANSI/AISC 358s1-11)
Commonly called the "prequalified connections standard," AISC 358 describes and provides design procedures for various moment connections for SMF and IMF applications. This standard is referenced by the AISC Seismic Provisions.

Keep your copy of the Seismic Design Manual and the AISC standards printed in Part 9 up-to-date. Periodically check here for revisions and errata.
These resources for the design of structural steel to resist seismic loads complement the Seismic Design Manual.
This primer (a free download) provides an overview of the causes of earthquakes, the earthquake effects that damage structures, the structural properties that are effective in minimizing damage, and the organization and intent of seismic design requirements for steel structures in the U.S. today.

Design Guide 20: Steel Plate Shear Walls
This design guide covers the background and design of steel plate shear walls for seismic and non-seismic applications. It includes design examples. Learn more here. Authors: Rafael Sabelli, S.E. and Michel Bruneau, Ph.D. PDF, 41 MB. 2006.
Design Guide 12: Modification of Existing Steel Welded Moment Frame Connections for Seismic Resistance
This design guide covers the rehabilitation of existing welded steel moment frame buildings to improve their seismic resistance in future earthquakes. Retrofit concepts with reduced beam section (RBS), welded haunch, and bolted bracket modifications are covered. Authors: John Gross, Michael Engelhardt, Chia-Ming Uang, Kazuhiko Kasai, and Nestor Iwankiw. PDF, 2 MB. 1999.
Design Guide 4: Extended End-Plate Moment Connections, Second Edition
The design guide makes use of yield line theory in a new design philosophy extended end-plate moment connections in wind and seismic applications. This allows extends end-plate moment connections to be designed using 50 ksi steel. Authors: Thomas M. Murray and Emmett A. Sumner. PDF, 3 MB. 2003.
FEMA 350 - Recommended Seismic Design Criteria for New Steel Moment-Frame Buildings
(superseded by AISC 358)
This resource document provides recommended guidelines for the design and construction of steel moment frame buildings and alternative performance-based design criteria. It supplements the NEHRP Recommended Provisions for Seismic Regulations for New Buildings and other Structures. A series of pre-qualified connection details, as well as a detailed procedure for performance evaluation, is included. This document is located on a FEMA server. PDF, 2.4 MB. 2000.

FEMA 353 - Recommended Specifications and Quality Assurance Guidelines for Steel Moment-Frame Construction for Seismic Applications
(superseded by the AISC Seismic Provisions and AWS D1.8)
This resource document has been prepared by the SAC Joint Venture, under contract to the Federal Emergency Management Agency, to indicate those standards of workmanship for structural steel fabrication and erection deemed necessary to achieve reliably the design performance objectives contained in FEMA 350, 351, and 352. This document is located on a FEMA server. PDF, 1.75 MB. 2000.
