Abstract:
Various reinforcement types can be evaluated to determine their relative performance in controlling the restrained shrinkage cracking behavior of concrete. Two sets of published test data on restrained shrinkage cracking of slabs-on-ground are analyzed, and a parameter suitable for comparing the performance of various reinforcement types is identified.

NEx: An ACI Center of Excellence for Nonmetallic Building Materials held a full-day technical workshop on “Design of GFRP-Reinforced Slabs-on-Ground and Paving” at the ACI Concrete Convention in Toronto, ON, Canada, on March 31, 2025. In addition, NEx hosted an exclusive lunch for members, speakers, and industry leaders to connect.

This article introduces the latest fiber-reinforced polymer panel system developed by the author—SPiRe®+. These panels can serve as formwork, corrosion resistant reinforcement, and waterproofing. With their flat and smooth exterior face and protruding T-profiles on the interior face, the panels act as reinforcing elements for strengthening beams, slabs, and walls.

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.

Symposium Papers
365
This Symposium Volume reports on the latest advancements related to the various facets of modeling and performance assessment of concrete structures. The volume contains 10 papers that were presented at the ACI Convention held in Toronto on April 1st, 2025. The symposium was dedicated to celebrate Prof. Frank J. Vecchio’s extraordinary research contributions and accomplishments in the development of behavioral models and analytical tools for the assessment of concrete structures. The papers cover different aspects related to modeling and performance assessment of concrete structures including developments of the Modified Compression Field Theory, finite element modeling of punching shear in slabs, behavior and modeling of steel fiber reinforced concrete members subjected to torsion, modeling of concrete structures subjected to impact loading, behavior and modeling of slender walls, modeling of concrete frame elements, behavior and modeling of GFRP reinforced members, crack-based assessment of concrete structures, and advancements in modeling deterioration mechanisms and repaired concrete structures. Sincere acknowledgements are extended to all authors, speakers and reviewers as well as to ACI staff for making this symposium a success. Anca-Cristina Ferche, Editor Vahid Sadeghian, Editor
