Abstract:
This article, the fourth in a five-part series on calculating deflections using a new expression for the effective moment of inertia Ie introduced into ACI CODE-318-19, provides a deflection example. The example follows the procedure outlined in Part 1 to compute the deflection of reinforced concrete (nonprestressed) one-way slab with both ends continuous.

This is the third article in a five-part series. While Parts 1 and 2 review the procedure and basis for computing deflection of reinforced concrete with a new expression for the effective moment of inertia Ie first adopted in ACI CODE-318-19, this article examines the implications of this change for satisfying deflection limits of beams and one- and two-way slabs. A need is seen to revise current minimum thickness values for beams.

This is the second article in a five-part series on calculating deflections for members not meeting minimum thickness requirements in accordance with ACI CODE-318-19. It reviews the development of a new expression for the effective moment of inertia Ie used to calculate immediate deflection of cracked reinforced (nonprestressed) concrete flexural members at service load and justifies the need for a change.

Serviceability is considered a critical factor in the management of concrete bridges and structures. Typical components for evaluating the serviceability limit state include cracking, deflection, and vibration. Additionally, to ensure the adequate performance of load-bearing members, proper evaluation methodologies should be adopted. Although numerous research projects have been undertaken to examine the serviceability and performance assessment of concrete bridges and structures, significant endeavors are still required to address unexplored challenges. Of interest are the development of simplified prediction and appraisal approaches; novel techniques for quantifying stress levels; serviceability criteria under unusual distress; and the characterization of structural responses when exposed to blast, wind, and seismic loadings. This Special Publication contains 11 papers selected from technical sessions held in the ACI Fall Convention in November 2024. The Editors wish to thank all contributing authors and anonymous reviewers for their rigorous efforts. The Editors also gratefully acknowledge Ms. Barbara Coleman at ACI for her knowledgeable guidance. Yail J. Kim, University of Colorado Denver, Editor Hyeon-Jong Hwang, Konkuk University, Editor
