This publication provides information for the engineering design and analysis of beams, one-way slabs, footings, pile caps, columns, and seismic design in accordance with ACI 318-05. Information is presented in three sections: Explanatory Material, Design Examples, and Design Aids. The Introduction of each chapter includes explanatory material that provides the engineer with concise background of the subject. The Design Examples illustrate the use of the Design Aids, which are tables and graphs intended to eliminate routine and repetitious calculations.
