Hello,
I'm finding a discrepancy between Profis and the Hilti design tables when running a calc for an anchor into masonry.
For a 3/4" dia. KH-EZ with 4" embedment into solid grouted masonry gives the following results...
Profis: Va = 2,432 lb
Hilti load tables = 3,040 lb
The two values are off by exactly 25%. Can you help me understand where the difference comes from. See attached for my results.
Hi Patrick,
PROFIS is correctly referencing an older version of ESR-3056 that is no longer published in ASD methodology. The difference in values between what is shown in PROFIS and in the Technical Guide is due to differing safety factors. The correct safety factor to use is ultimately up to the judgement of the Engineer of Record on the project. For further information and questions, please contact hnatechnicalservices@hilti.com.
Regards,
Katelyn
