Fiberglass rebar (in the codes as glass fiber reinforced polymer [GFRP]) is an amazing product that had quite a banner year in terms of incorporation into U.S. building codes

Why Fiberglass Rebar?

• Easier to cut and manipulate
• 75% lighter = fewer deliveries and less heavy lifting
• Stronger: 2x-3x the strength
• Longer-lasting: no corrosion

All told you save on operational costs. And at the moment you also save over black steel on material costs.

TMS 402/602

• With the addition of appendix D, GFRP can be used in non-loadbearing masonry walls. This make it ideal for fire escapes, elevator shafts, and retaining walls.
• No impact on a masonry wall’s fire rating
• No need to bend at the footer because the bar doesn’t corrode when in contact with the ground. Development length of a a straight bar 20x its diameter (e.g., 1/2″ bar should go in 10″)
• Replace the steel bar with an equal diameter bar that meets ASTM D7957 (#4 steel –> 4MAX)

ACI 440.11

• Codifies what has been a design guide for 15+ years
• Explains use in most concrete structures, with some exceptions (e.g, high seismic zones)
• Offers suggested reinforcement details
