RE: -- SPAM -- Deformed bars - Permissible variation in weight

[Subject Prev][Subject Next][Thread Prev][Thread Next]



If they are underweight, but the correct diameter (I don’t know), I would wonder what material is in the bar to make it too light.  Has the strength been tested?

We have a situation where the test results give under weight bars (approx 15%), exceeding the 6% permissible variation in weight by ASTM. If we account for the reductions in weight/diameter by decreasing spacings and providing ample steel area, is there any codal provision restricting it.
