PREFACE
The primary objective of this Companion is to provide guidance and additional resources of the use of the 2016AISC Specificarion for Structural Steel Baildings (ANSI/AISC 360-16) and the 15th Edition AISC Steel Construction Marual.
The Companion consists of design examples in Parts I II and II and design tables in Part IV. The design examplesprovide coverage of all applicable limit states whether or not a particular limit state controls the design of themember or connection. In addition to the examples that demonstrate the use of the AISC Muual tables design examples are provided for connection designs beyond the scope of the tables in the AISC Manual. These designexamples are intended to demonstrate an approach to the design and are not intended to suggest that the approach presented is the only approach. The mitte responsible for the development of these design examples recognizesfrom those presented in these examples are considered viable as long as the AISC Specification sound engineering that designers have altemate approaches that work best for them and their projets. Design approaches that differ
Part I of these examples is organized to correspond with the organization of the AISC Specjfication. The Chaptertitles match the corresponding chapters in the AISC Specijficarion.
Part I is devoted primarily to connection examples that draw on the tables from the AISC Manual Part IV of this publication remended design procedures and the breadth of the AISC Specifcarion. The chapters of Part II arelabeled II-A II-B II-C etc.
Part Ill addresses aspects of design that are linked to the performance of a building as a whole. This includesframe building. coverage of lateral stability and second-order analysis illustrated through a four-story braced-frame and moment-
Part IV provides additional design tables beyond what is incorporated into the AISC Maruaaf.
The Design Examples are arranged with LRFD and ASD designs presented side-by-side for consistency with the AISC Manual. Design with ASD and LRFD are based on the same nominal strength for each element so that theonly differences between the approaches are the set of load binations from ASCE/SEI 7-16 used for design and whether the resistance factor for LRFD or the safety factor for ASD is used.
CONVENTIONS
The following conventions are used throughout these examples:
1. The 2016 AISC Specification for Strucfural Steel Builedings is referred to as the AISC Specificarion and the 15th Edition AISC Steel Constraction Manuol is referred to as the AISC Marual.2. The 2016 ASCE Minimum Design Loods and Associated Criteria for Buildings and Other Structures is referred to as ASCE/SEI 7.3. The source of equations or tabulated values taken from the AISC Specification or AISC Manual is notedalong the right-hand edge of the page.4. 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 and the safety factor Ω are applied.5. The results of design equations are presented to three significant figures throughout these calculations.
