PREFACE
The AISC Design Examples CD provides examples on the application of the 2005 AISC Specification for Structural
Steel Buildings (ANSI/AISC 360-05) and the AISC Steel Construction Manual, 13th Edition. The examples found
herein illustrate how the Specification and Manual can be used to determine solutions to common engineering
problems efficiently, and outline the background to many of the tabulated values found in the Manual.
The design examples on this CD do not represent a stand-alone document. They are intended to be used in
conjunction with the Specification, its Commentary, and the Manual.
Part I of these examples is organized to correspond with the organization of the Specification and the Chapters are
referred to by their corresponding letter reference from the Specification.
Part II is devoted primarily to connection examples that draw on the tables from the Manual, recommended design
procedures, and the breadth of the Specification. The chapters of Part II are labeled II-A, II-B, II-C, etc.
Part III addresses aspects of design that are linked to the performance of a building as a whole. This includes
coverage of lateral stability and second order analysis, illustrated through a four-story braced-frame and momentframe
building.
The Design Examples are arranged with LRFD and ASD designs presented side by side, for consistency with the
Manual. Design with ASD and LRFD are based on the same nominal strength for each element so that the only
difference between the approaches is which set of load combinations from ASCE 7 are used for design and whether
the resistance factor for LRFD or the safety factor for ASD should be used.
CONVENTIONS
The following conventions are used throughout these examples:
1. The 2005 AISC Specification for Structural Steel Buildings is referred to as the Specification and the AISC
Steel Construction Manual, 13th Edition, is referred to as the Manual.
2. The source of equations or tabulated values taken from the Specification or Manual is noted along the righthand
edge of the page.
3. When the design process differs between LRFD and ASD, the designs equations are presented side-by-side.
This rarely occurs, except when the resistance factor, φ, and the safety factor, Ω, are applied.
4. The results of design equations are presented to 3 significant figures throughout these calculations.
