What is the Ultimate Strength for different sizes of Rebar?
“Ultimate Strength” refers to per unit values. It is a physical property of the material itself that applies to all sizes and shapes into which the material may be formed. Tests indicate that the Ultimate Strength of the FRP rebar is approximately 160,000 psi maximum. The “breaking strength” of various sizes of rebar can vary in inverse relation to bar size – from 160,000 psi for smaller sizes, to 100,000 psi for larger bars. How do you use FRP rebar in beam and slab design? The designer is simply using a material with different physical properties. As a result of the difference in the physical properties (in this case a lower value of E), he will arrive at different amounts of reinforcements, beam sizes, column dimensions, etc. than if he were designing in other materials. How do you tie the bars together? Cable ties of plastics clips. Can the FRP rebar be bent by the customer? No. Resins are cross-linking thermo-sets. Cure is a chemical reaction, not a change of physical state. All A
