Where is the best place to look up definitions in ACI 318-14?

The best place to look up definitions in ACI 318-14 is Chapter 2. This chapter is specifically dedicated to definitions and terminology, providing clarity and context for the various terms used throughout the document. Understanding the definitions in this section is essential for correctly interpreting the standards and guidelines presented in the code. By referring to Chapter 2, readers can ensure they have a solid grasp of key concepts that are crucial for the application of reinforced concrete principles.

The other chapters mentioned do contain important information related to concrete design, codes, and standards, but they do not serve the specific purpose of defining terminology. For example, Chapter 5 focuses on structural analysis and design, while Chapter 9 addresses the details and requirements for special structures. Appendix A may contain supplementary material or additional information, but it does not serve as the primary source for definitions as Chapter 2 does.
