ACI 318-14 strength design provisions for shear check a calculated design strength ( ϕV N
) against a factored shear load ( V ua
).
Reference the Equations section of the PROFIS Engineering report for more information on the following parameters :
V cp
: 1 Nominal concrete pryout strength in shear
ϕV cp
: 1 Design concrete pryout strength in shear ϕV cp
≥ V ua
: 1 Design check for pryout
Reference the Results section of the PROFIS Engineering report for more information on the following parameters :
V cp
: 1 Nominal concrete pryout strength in shear
ϕ concrete
: 1 Strength reduction factor for concrete failure
ϕ seismic
: 1 Strength reduction factor for seismic shear
V ua
: 1 Factored load acting on anchors in shear
A summary of calculated shear design strength versus the factored shear load for each shear failure mode relevant to the application is given in Part 4 Shear Load of the PROFIS Engineering report .
