ACI committee 440 is the most authoritative and prolific consensus standards body involved in the publication of design guidelines for the use of FRP bars.
Hughes Brothers has been an active participant in 440 committee activities since 1994. Committee 440 documents are based on research performed world-wide.

For structural strengthening using Aslan 400 CFRP Laminates, design guidance is provided in the ACI 440.2R-08 "Guide for the Design an Construction of Externally Bonded FRP Systems for Strengthening Concrete Structures".
To aid the designer unfamiliar with the various FRP design guides and standards, Hughes Brothers has engineering assistance available in house. Our staff of engineers are intimately involved in the authorship of the various design guides, standard and test methods and are available to help with your specific project.
We will NOT stamp designs, rather we are here to "compliment" your efforts for a successful implementation of Aslan FRP bars.
Using industry standard consensus design methods, we will furnish you with a design proposal based on the inputs you provide us. Hughes Brothers will not perform any structural analysis and our scope is limited to design advice only to the engineer of record concerning implementation of Aslan FRP materails.

To assist you, our staff needs a clear understanding of:
- Geometry of the concrete member -- electronic or CAD drawings are most helpful
- Moment and shear forces the member is subject to
- Concrete strengths
- Locations of existing internal reinforcing
- Existing capacities and amount of increased capacity being designed for
