Hilti Profis Shear Reinforcement

[Keystation]

I am designing a column with high shear and moment. I used a shear lug and it's calculating for concrete breakout in shear by shear lug. However, it's still failing. So I clicked on shear reinforcement for anchors but that didn't do anything. Is this because shear lug is meant to take all the shear load? My question is can I just shear reinforce the anchors along with shear lug? The concrete base is 2ftx2ft (I wish there were more space but this is the best). The depth is large enough. Thank you in advance

The shear lug is for this intent an 'anchor'. You can attempt to reinforce the anchor against breakout in shear. Hilti doesn't provide any guidance on this you need to refer to ACI or the Widianto et al for a rational method to do this.

@driftLimiter is correct. The anchor design software (hilti/simpson/etc) doesn't design the anchor reinforcement (at least not the last time I used them).

HILTI has the ability to design anchor reinforcement (not sure if to ACI, but to eurocode it does). Some of the confusion is the terminology - in America "anchor reinforcement" is the term used to denote reinforcement thats designed to take all the anchorage loads, whereas in the rest of the world and among much of the literature this is generally denoted as "supplementary reinforcement" (which in the ACI means something different). If you lookup "HILTI supplementary reinforcement" you will be able to find some ask HILTIs and PDFs online from them about this, as well as how it is implemented in PROFIS for Eurocode checks which may point you in the right direction. They may have also got this for ACI in PROFIS but I haven't looked into it. Alternatively you design by hand using the principles in the code.
