limitation of fy used in ACI shear friction calculation
limitation of fy used in ACI shear friction calculation
(OP)
Hi,
Can anyone tell me why ACI 318-05 section 11.7.6 limits the value of reinforacement "fy" to 60 ksi for the shear friiction calculation? I am hoping to use high strength dowels with fy=120 ksi to increase the shear friction capacity. Thanks!

RE: limitation of fy used in ACI shear friction calculation
Much of the shear friction research was probably limited to 60 ksi bars and the resulting formula based on that research. Since 60 ksi steel and 120 ksi steel have the same modulus of elasticity, E, the behavior using higher strength bars doesn't do you any good....that's my guess anyway.
