Where can immediate and long-term deflection analysis for concrete be found?

The correct answer is found in ACI Chapter 24, which specifically addresses issues related to deflections in concrete structures. This chapter provides comprehensive guidelines and formulas for analyzing both immediate and long-term deflection behavior in concrete beams and slabs, incorporating factors such as creep and shrinkage. Understanding deflection is crucial for ensuring structural performance and serviceability, as excessive deflection can lead to structural damage and affect the functionality of the space.

The content of ACI Chapter 24 is instrumental in design practices, as it lays out the necessary standards and considerations engineers need to comply with to predict how concrete elements will behave under loads over time. This chapter is pertinent for compliance with serviceability requirements set forth in building codes.

Other chapters mentioned may cover various aspects of concrete design and construction, but they are not specifically focused on deflection analysis. For instance, Chapter 13 deals with shear and torsion, Chapter 30 addresses connections, and Chapter 18 discusses the design of structural elements. These topics, while important, do not directly pertain to the immediate and long-term deflection of concrete, making Chapter 24 the correct source for the sought-after analysis.
