Revised and updated in September 2004, this book incorporates significant and sweeping changes introduced in the ACI 318-02 Building Code such as new load and resistance factors, and unified design provisions. New to this edition is a chapter dedicated to the seismic load calculations and design considerations. Loading provisions, including earthquake, are in accordance with the 2003 Edition of the International Building Code (IBC 2003) and the American Society of Civil Engineers Standard ASCE 7-02 for Minimum Design Loads.

Simplified equations, design aids, graphs, and clarification of code requirements are provided throughout for use by engineering professionals seeking ways to speed and simplify their design procedures. Numerous solved examples illustrate the use of the simplified methods and are compared with exact analysis results from PCA concrete design software.

The publication contains eleven chapters covering the design and requirements for beams, one-way slab, two-way slab systems, columns, structural walls, footings, structural detailing, formwork, and fire resistance. Chapter Eleven on design consideration for earthquake forces is new to this edition. The seismic design provisions of the International Building Code (2003 IBC) are introduced in this chapter.
