Hi Tianxiang,
The capacity comes from testing per the acceptance criteria, AC193, which is then published in ICC ESR-3027. Please reference Table 5 in the ESR linked for more information on the steel strength capacity. Additionally, the phi factors used in the calculations can be found in Table 3 of the same report. If you have additional questions please feel free to reach out to Hilti's engineers at 877-749-6337 or hnatechnicalservices@hilti.com.
Regards,
Dani
