Tensile Strength of Rebar Reinforcement
Tensile Strength of Rebar Reinforcement
(OP)
Hi all struc eng,
BS 4449 and Annex C of EC2 gives a table on the characteristic values/properties of reinforcement (tensile strengths).
For example: Grade 500B : Rm/Re is > 1.08
On BS 4483 and EN 10080 another table is given having a Minimum and Maximum absolute values. This time for:
Grade 500B: Rm/Re is 1.06
Therefore if one had to test a rebar having Rm/Re is 1.07, should one grade it as 500A or 500B? Which table shall one you as a lower limit?

RE: Tensile Strength of Rebar Reinforcement
Assuming ductility is a good thing, then I would read Table 4 of BS4449 as the minimum Rm/Re that it needs to achieve to be grade B500B.
In your case if you have a bar (not mesh) I would grade it as B500A to BS4449 because it doesn't meet the requirement for B500B.

RE: Tensile Strength of Rebar Reinforcement
Should one use the table of BS4483 or table 4 of BS4449.
