Abstract:

Teaching college students advanced concrete materials and structural concrete design is a challenging task because students have a myriad learning styles, and instructors are often ill equipped to meet students where they are with appropriate experience and teaching-related resources. This disconnect can create several bottlenecks to learning, especially within courses that present advanced concrete topics that are more complex and challenging. This paper outlines a special publication series related to best practices and lessons learned for teaching advanced concrete materials and structural design by experts in the field from across the United States. Furthermore, this introductory paper outlines the history of teaching and learning resources at the American Concrete Institute (ACI) and provides a high-level overview of other technical concrete-focused resources and teaching development resources that can be used to bridge the gap between teaching and learning challenging concrete subjects. The goal of this special publication is to provide a resource for anyone that accepts the challenge of teaching advanced concrete materials and structural design, from a new instructor to an experienced professor.

Abstract:

The City of St. Thomas, ON, Canada, erected a concrete statue of Jumbo the Elephant in 1985 to commemorate the 100th anniversary of the circus elephant’s tragic death in St. Thomas after being struck by a train. This article is the first in a series by ACI Committee 120, History of Concrete, about commemorative monuments across North America and around the globe that have been constructed using concrete.

Abstract:

“The Modern Concrete Skyscraper" exhibition at The Skyscraper Museum in New York, NY, USA, retells the history of the high-rise through the lens of reinforced concrete. CI staff were toured through the exhibit, gaining insight into the curation process; the inspiration, goals, and themes behind the exhibit; and its reception.

Abstract:

At the ACI Concrete Convention – Fall 2025 in Baltimore, MD, USA, ACI Committee 120, History of Concrete, held a special session titled, “Documenting Concrete History: A Tribute to Luke and Billie Snell,” commemorating their contributions to the success of the Committee. This article describes presentations given by six Committee members based on papers previously published by the Snells.

Abstract:

Retrofit of reinforced concrete bridge columns with steel jackets is a commonly implemented strategy to increase column ductility in earthquakes. If the steel jacket retrofit is designed using available guidelines, fatigue fracture of longitudinal reinforcement is a likely cause of strength degradation. Fatigue fracture in reinforcement is dependent upon strain history in reinforcement. A model was developed to determine the strain history in longitudinal reinforcement at the plastic hinge in steel jacket retrofitted reinforced concrete columns. The model was validated with existing test data, and single degree of freedom nonlinear time history analyses were conducted using the model. Earthquake duration was shown to have a significant impact on the number of plastic excursions and the total plastic strain in the reinforcement, based on the results of analyses using an existing suite of long-duration earthquake ground motions that were each paired with a short-duration ground motion with similar response spectra. Results from analyses of 600 Magnitude-9.0 Cascadia Subduction Zone simulated site-specific ground motions for western Washington State were used in the formulation of a new testing protocol for steel jacket retrofitted reinforced concrete bridge columns that better accounts for expected demands in this region.
