Figure 6.2.3f.
For the anchorage shown in Figure 6.2.3f [ 59 ], shear concrete breakout is checked for shear load acting towards the x- and y- fixed edges. The ACI 318 design check would be as follows:
MAX( V ua, x, col n / ϕV cbg, x, col n):( V ua, y, row n / ϕV cbg, y, row n)
The PROFIS Engineering design check would be as follows: MAX( V ua, res, col n / ϕV cbg, x, col n):( V ua, res, row n / ϕV cbg, y, row n)
Reference Corner – Concrete Breakout Parallel to y- Edge( page 27). When a corner condition such as that shown in Figure 6.2.3f [ 59 ] exists, concrete breakout with respect to shear load acting parallel to each fixed edge must also be considered. The ACI 318 design check assuming shear load acts parallel to each fixed edge would be as follows:
MAX
( V ua, y, col n / 2ϕV cbg, x, col n):( V ua, x, row n / 2ϕV cbg, y, row n)
The PROFIS Engineering design check assuming shear load acts parallel to each fixed edge would be as follows: MAX( V ua, res, col n / 2ϕV cbg, x, col n):( V ua, res, row n / 2ϕV cbg, y, row n)
The overall design for shear concrete breakout per ACI 318 provisions would be controlled by: MAX( V ua, x, col n / ϕV cbg, x, col n):( V ua, y, row n / ϕV cbg, y, row n):( V ua, y, col n / 2ϕV cbg, x, col n):( V ua, x, row n / 2ϕV cbg, y, row n)
The overall design for shear concrete breakout per PROFIS Engineering assumptions would be controlled by: MAX( V ua, res, col n / ϕV cbg, x, col n):( V ua, res, row n / ϕV cbg, y, row n):( V ua, res, col n / 2ϕV cbg, x, col n):( V ua, res, row n / 2ϕV cbg, y, row n)
The PROFIS Engineering design assumptions predicated on using V ua, res in lieu of V ua, x or V ua, y to calculate concrete breakout in shear are conservative.
