Abstract:
Recently, the ACI Foundation engaged with donor and Trustee Keith Kesner, discussing his journey and the driving force behind his support for the ACI Foundation. Later this year, the ACI Foundation’s Concrete Innovation Council will be hosting the Concrete Innovation Forum in Denver, CO, USA. The agenda for this year features six presentations, four technology showcases, and three panel discussions.

This paper reviews the state-of-the-art finite-element analysis (FEA) for reinforced concrete (RC) structures subjected to high-strain-rate deformation and focuses on RC panels subjected to impact loads. Despite extensive experimental studies on the impact behavior of RC panels, a robust concrete material model for accurate simulation of high-strain-rate scenarios is lacking. To address this gap, this study aims to identify the optimal concrete material model for predicting local damage in RC panels impacted by projectiles by simulating the collision of a large commercial aircraft with critical infrastructures, such as nuclear power plants. In this study, the theoretical foundations and parameters of concrete material models were examined to simulate realistically the local responses of RC panels subjected to dynamic loading, specifically focusing on hard projectile impacts at velocities ranging from 100 to 220 m/s (328 to 722 ft/s). Single-element analyses were conducted followed by finite-element simulations of scaled-down aircraft impact tests to assess the ability of the models to predict the failure modes, residual projectile velocities, and damaged areas. Among the four concrete models available in LS-DYNA, the concrete damage model (release 3) provided the best results for the four panels experimentally tested in this study.

Hosted by the Concrete Innovation Council (CIC), the session “Innovations in Concrete” will be held on March 30, 2025, at the ACI Concrete Convention – Spring 2025 in Toronto, ON, Canada. The theme is “Implementing Low Carbon Concrete – From Innovation to Reality.” Later this year, the ACI Foundation 2025 Concrete Innovation Forum will be held August 12-14, 2025, at the Hotel Clio, Denver, CO, USA. The focus will be on how new practices, materials, or inventions move from the lab to the field.

The ACI Foundation extends its heartfelt gratitude to all the generous donors who have made the 2024 Annual Appeal a resounding success. Looking to the new year, registration is open for the highly anticipated 2025 Concrete Innovation Forum, formerly known as the Technology Forum, on August 12-14, 2025, in Denver, CO, USA.
CI4702TechForum
To support ACI’s expanding focus on advancing the concrete industry, the ACI Foundation hosted a Technology Forum, an innovation-focused educational and networking events featuring presentations by researchers. This article is the last of three articles that summarize the presentations made at the 2024 Technology Forum.
