The 2009 IBC Structural/Seismic Design Manual provides a step-by-step approach to properly applying the structural/seismic provisions of the 2009 International Building Code. This new edition has been completely updated to reflect the latest design methods contained in the 2009 International Building Code and applicable referenced standards. The manual's 57 examples illustrate the practical application of a broad base of problems addressing both structural and seismic design issues.

Volume 1 contains code application examples, including determination of seismic irregularities, combination of structural systems, determination of drift, support of discontinuous systems, and analysis of seismic forces applied to equipment, non-structural elements and non-building structures.

Volume 1: Code Application Examples includes:

• Sample structures
• ASCE 7 equations applied to examples
• Code and standard references for each example

An excellent reference and study guide for the NCEES Structural Exam. This manual is an invaluable resource for structural and civil engineers, architects, and students.

From the Introduction
Volume I of the 2009 International Building Code Structural/Seismic Design Manual: Code Application Examples deals with interpretation and use of the structural/seismic provisions of the 2009 International Building Code. The 2009 International Building Code Structural/Seismic Design Manual is intended to help the reader understand and correctly use the 2009 International Building Code structural/seismic provisions and to provide clear, concise, and graphic guidance on the application of specific provisions of the code. It primarily addresses the major structural/seismic provisions of the 2009 International Building Code, with interpretation of specific provisions and examples highlighting their proper application.

The 2009 International Building Code has had structural provisions removed from its text and has referenced several national standards documents for structural design provisions. The primary referenced document is ASCE/SEI 7-05, which contains the Minimum Design Loads for Buildings and Other Structures. ASCE/SEI 7-05 is referenced for load and deformation design demands on structural elements, national material design standards (such as ACT, AISC, MSJC and NDS) are then referenced to take the structural load demands from ASCE/SEI 7-05 and perform specific material designs.

Volume I presents 58 examples that illustrate the application of specific structural/seismic provisions of the 2009 International Building Code. Each example is a separate problem, or group of problems, and deals primarily with a single code provision. Each example begins with a description of the problem to be solved and a statement of given information. The problem is solved through the normal sequence of steps, each of which is illustrated in full. Appropriate code references for each step are identified in the right-hand margin of the page.

The complete 2009 International Building Code Structural/Seismic Design Manual will have three volumes. Volumes II and III will provide a series of structural/seismic design examples for buildings illustrating the seismic design of key parts of common building types such as a large three-story wood frame building, a tilt-up warehouse, a braced steel frame building, and a concrete shear wall building.

While the 2009 International Building Code Structural/Seismic Design Manual is based on the 2009 International Building Code, there are some provisions of SEAOC's Recommended Lateral Force Provisions and Commentary (Blue Book) that are applicable. When differences between the 2009 International Building Code and Blue Book are significant, they are brought to the attention of the reader.

The 2009 International Building Code Structural/Seismic Design Manual is intended for use by practicing structural engineers and structural designers, building departments, other plan review agencies, and structural engineering students.

From the Preface
This document is the initial volume in the three-volume 2009 International Building Code Structural/Seismic Design Manual. It has been developed by the Structural Engineers Association of California (SEAOC) with funding provided by SEAOC. Its purpose is to provide guidance on the interpretation and use of the seismic requirements in the 2009 International Building Code, published by the International Code Council, Inc., and SEAOC’s 2005 Recommended Lateral Force Requirements and Commentary (also called the Blue Book).

The 2009 International Building Code Structural/Seismic Design Manual was developed to fill a void that exists between the recommendations of the Blue Book, which explains the basis for the code provisions, and everyday structural engineering design practice. The 2009 International Building Code Structural/Seismic Design Manual illustrates how the provisions of the code are used. Volume I: Code Application Examples, provides step-by-step examples for using individual code provisions, such as computing base shear or building period. Volumes II and III: Building Design Examples furnish examples of seismic design of common types of buildings. In Volumes II and III, important aspects of whole buildings are designed to show, calculation-by-calculation, how the various seismic requirements of the code are implemented in a realistic design.

The examples in the 2009 International Building Code Structural/Seismic Design Manual do not necessarily illustrate the only appropriate methods of design and analysis. Proper engineering judgment should always be exercised when applying these examples to real projects. The 2009 International Building Code Structural/Seismic Design Manual is not meant to establish a minimum standard of care but, instead, presents reasonable approaches to solving problems typically encountered in structural/seismic design.

The example problem numbers used in the prior manual - 2006 IBC Structural/Seismic Design Manual: Volume 1: Code Application Examples - have been retained herein to provide easy reference to compare revised code requirements.

SEAOC and ICC intend to update the 2009 International Building Code Structural/Seismic Design Manual with each edition of the building code.
