ϕV cp
≥ V ua
Reference the Results section of the PROFIS Engineering report for more information on the following parameters :
V cp
: nominal concrete pryout strength in shear
ϕ concrete
: strength reduction factor for concrete failure
ϕ seismic
: strength reduction factor for seismic shear
ϕV cp
: design concrete pryout strength in shear
V ua
: 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 .
