Your software states that cracked needs to be considered if the anchor is not within the compressive zone - this limits this application to very few scenarios.
Is there a work around or an alternative product that can be utilised to resolve? Assume i can share the profis model?
Thanks for your enquiry, the software is following the criteria set out in EC2 Part 4 Design of concrete structures, Design of fastenings for use in concrete Section 4.7 Determination of concrete condition. Now if you are wishing to comply with this code and you follow the checks in this section and confirm you concrete is in compression then you can simply change the concrete from cracked to uncracked in the software and run the calculation.
Thanks for the follow up. The issue from looking at your file isn't whether your concrete is cracked or uncracked but a Steel failure of the anchor rod at 156% utilisation due to the lever arm .Please see page 4 of your pdf report and concrete edge failure at 135%. For the steel, easiest option is to remove or reduce the 16mm leveling grout thickness otherwise if not an option revisit the number of anchors or assess if your loads are conservative or not. Now if the concrete has not yet been cast you could depending upon the concrete area look at using supplementary reinforcement to improve the shear edge resistance. You will find a webinar on the askhilti site re this subject and shear loads.
Hi Thomas, Please check out the webinar here Supplementary reinforcement in shear - Ask HILTI
and to confirm M20 is largest bolt size for HIT-HY-200-A HAS-D arrangement?
Hi, 20mm is the largest diameter HAS-D rod available for fatigue loading to EC2 & TR061 and for static / quasi static and seismic C1 & C2 to EC2 & TR055
Hi, The main failure modes were the steel and edge failure, as mentioned supplementary reinforcement can assist in some design cases especially if the base hasn't yet been cast.
Hi, I'd suggest getting in contact with you local regional HILTI office . They will be able to assist you directly or arrange for your local engineer to contact you directly if you would prefer . There is no chat / telephone facility on this forum.
