Our team presented at the PCI 2026 Convention in Kansas City an experimental study involving more than 70 test specimens of adhesive anchors embedded in thin ultra-high performance concrete (UHPC) panels. The work examined the effects of anchor diameter, panel thickness, fiber type (steel and synthetic), fiber volume fraction, and related parameters on anchor performance. The experimental program and testing efforts were led by PhD student Pramashis Kar.

Publication alert: this paper investigates the effects of strain rate on the bond behavior between FRCM composites and concrete substrates. Special thanks to former MSc student, Lucas Gervais, for leading the experimental program and carrying out the testing with exceptional rigor. Thank you to our graduate team members for their contributions, as well as our industrial partners, Simpson Strong-Tie and Kyowa Americas Inc, for in-kind support.
The collaboration with NEx: An ACI Center of Excellence for Nonmetallic Building Materials in the development of the FRCM guideline was instrumental in identifying the research gap addressed in this study.

New publication alert: State of the art review of machine learning applications for bridge inspections; thanks to Amr Ashmawi, and Dr. Phuong Nguyen, Ph.D. for their outstanding contributions to this work.
The SAR paper reviewed over 60 technical articles and summarized various advanced inspection tools—such as Unmanned Aerial Vehicles (UAVs), digital imaging, and fiber optic sensors—as well as ML and AI models for data processing and damage detection used in bridge inspection and maintenance. The review demonstrated ML’s ability to integrate these advanced tools to improve data accuracy, decision-making, and inspection efficiency, while also highlighting the challenges that still remain.
New Publication Alert: Rubberized Concrete Columns – Free Access for 50 Days!
A joyous start to 2024, four of our articles were published this January in reputable journals, focusing sustainability and resilience of the built infrastructure, for example investigating hybrid members made of ultra-high performance concrete (UHPC) and conventional concrete, UHPC beam-column joints under cyclic loading. Credit goes to the students and collaborators whose hard work and dedication made this possible.
