β V
The PROFIS Engineering anchor portfolio includes post-installed mechanical anchors , postinstalled adhesive anchors , and cast-anchors . The following shear failure modes are considered for each type of anchor :
post-installed mechanical anchor |
steel strength : |
β V
= V ua ( i ) / ϕ steel
V sa
|
concrete breakout strength : |
β V
= V ua ( i ) / ϕ concrete
V cb or β V = V ua ( g )
/ ϕ concrete
V cbg
|
concrete pryout strength : |
β V
= V ua ( i ) / ϕ concrete
V cp or β V = V ua ( g )
/ ϕ concrete
V cpg
|
post-installed adhesive anchor |
steel strength : |
β V
= V ua ( i ) / ϕ steel
V sa
|
concrete breakout strength : |
β V
= V ua ( i ) / ϕ concrete
V cb or β V = V ua ( g )
/ ϕ concrete
V cbg
|
concrete pryout strength : |
β V
= V ua ( i ) / ϕ concrete
V cp or β V = V ua ( g )
/ ϕ concrete
V cpg
|
cast-in anchor steel strength : concrete breakout strength : concrete pryout strength : β V
= V ua ( i ) / ϕ steel
V sa β V
= V ua ( i ) / ϕ concrete
V cb or β V = V ua ( g )
/ ϕ concrete
V cbg β V
= V ua ( i ) / ϕ concrete
V cp or β V = V ua ( g )
/ ϕ concrete
V cpg where V ua ( i ) corresponds to the highest factored shear load acting on an individual anchor and V ua ( g ) corresponds to the total factored shear load acting on a group of anchors .
