This extensively revised and updated fourth edition provides engineers with the principles and tools needed to turn their familiarity with earlier ACI Codes into more profitable, timesaving routine designs. Created to be used with the ACI Code and Commentary, this guide follows the new Code format with information covered in more specific sections and sub-sections to enhance clarity. In addition, it shortens time for computer-aided design and analysis, converts code formulas from the review form to direct design, and presents simple formulas, tabulations, and charts for conservative long-hand direct design. Two convenient indices - a subject index and a 1995 Code section index - are provided, enabling engineers to quickly locate all Code references to a particular topic, as well as concise interpretation of a given Code section.
