Abstract:
This article is a response to “Brittle Failures in Precast Parking Structures” by William L. Gamble, Gordon H. Reigstad, and Jason Reigstad, published in CI in September 2019. It provides discussion on the original design concept for prestressed concrete double-tees with flanges reinforced primarily with carbon-fiber-reinforced polymer grid, their development and evaluation, and flange failures. A closure from the authors of the September 2019 CI article is also provided.
