Abstract:
This is the last article in a five-part series on calculating deflections for members not meeting minimum thickness requirements in accordance with ACI CODE-318-19. The Code’s approach for calculating immediate deflection of reinforced (nonprestressed) concrete is broadened to include prestressed concrete loaded above the cracking moment (Class T and Class C prestressed members).

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.

Hollow-core (HC) slabs are precast/prestressed concrete members with continuous voids oriented parallel to the span of the slabs. Openings in HC slabs are one of the most common challenges encountered during construction. This study experimentally evaluated the effectiveness of proposed strengthening methods for HC slabs with unforeseen structural openings.

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.
