How do I access the QUIZ, following webinar AC201 (that was hosted on May 5, 2026)? The link that was sent to me by email is not working.

I noticed on ACI 318 chapter 17, they use 0.65*As*Fu, and the design sometimes relies heavily on concrete breakout capacity. Is there any way we can design chemical anchor to be able to reach its steel yielding poi...

We noticed on the hilti website when searching at https://www.hilti.com/c/CLS_FASTENER_7135/CLS_CHEMICAL_ANCHORS_7135 and clicking on the down arrow by specifications for each the -A and -R product type that only -A shows acceptable for grout-filled masonry.

This note also appears in the ESR-4236 for those anchors. However, other HILTI docume...

I am evaluating an existing structure that used HIT-RE 500 SD epoxy for it's anchors. I am trying to determine whether it is adequate for new loads, and acceptable for our high seismic zone. Was HIT-RE 500 SD tested and approved for cracked concrete? Do you have the historic capacity information?

Can you please explain to me why I am not receiving any PDH Certificates per my email for attending your Hilti webinar sessions?

Where can I find your intumescent paint volume calculator?
