Pullout Capacity of Expansion Anchors
Why does Expansion Anchors such as HST3 & HSL4 (of certain diameters) does not have pullout capacity in Profis Engineering. Please elaborate explanation on the ESR "pullout strength in tension need not be evaluated".

Hello Philip,
Thank you for reaching out to Hilti.
Pull-out in tension mainly depends on the anchor quality, the cracked condition of the concrete and the concrete class.
In instances where pull-out is not deemed decisive by evaluation to ACI 355.2, the underlying assumption is that concrete cone breakout occurred before pull-out could be achieved. Hence, the ESR does not publish this value.
Hope this helps.
Kind Regards,
