Calculation for Concrete Breakout (HILTI PROFIS Engineering 3.0.81)

Thanks for the screen shots from what I can see the issue is the width of the concrete. Following the design concepts of a rough V shaped area protruding from the anchors lines you have reductions for the two side edges plus the bottom edge loaded edge. For example, remove your middle row of 3 anchors reduce the diameters down to M24 and your concrete edge breakout reduces by about 70%.

Now if you you can see the edge influence even more now if you assume for now the 975mm edge cannot fail so call it infinity. Does the connection now work? The answer is no you still have concrete failure at over 200% approx.
Checking the steel and the bond checks the anchors are fine but the limitation is the base material. If the base has not yet been cast you could look to see if supplementary reinforcement could assist. Please see the online videos on askhilti re this approach. Could the concrete strength be enhanced? Are the fixings in the tensile zone of the concrete? Is the load applied conservative etc ?

Again, it could be when you've checked this you still do not have a workable solution and a different design approach may need to be considered such as a shear keys thereby transferring the shear into bearing within the concrete, but this is an approach outside of our remit. Any post installed anchors would then just be to deal with any tensile load and would need to be positioned so that they did not become loaded under a shear condition.
