NEx Webinar Series: GFRP Adhesive Anchors for Concrete Structures

November 19, 2025 to November 19, 2025

Starting Time:   1:00PM EST

End Time:   2:00PM EST

Sponsor(s): ACI and NEx

Description:
This webinar is jointly sponsored by NEx: An ACI Center of Excellence for Nonmetallic Building Materials and the American Concrete Institute (ACI).

Anchoring to concrete is a common structural application in new and repair construction. The use of post-installed glass fiber reinforced polymer (GFRP) reinforcing bars or anchors for connecting concrete placed at different times can provide a durable structural solution when constructing in environments exposed to seawater, deicing salts, and stray electrical current. However, current codes lack guidance for the design of post-installed GFRP bars or anchors using structural adhesive. Drawing from over 400 experimental tests and comparative analysis with ACI 318 provisions for steel anchors, the session explores failure modes, bond behavior, and design strengths specific to post-installed GFRP adhesive bars or anchors. Attendees will gain insight into practical applications, research gaps, and draft code language tailored for GFRP adhesive anchors. This presentation is ideal for engineers, researchers, and code developers seeking to advance non-metallic anchorage solutions in concrete construction.
