Fire stop in electrical conduit

Wondering why the pullout strength for concrete is not considered for design in the software as well in Table-4 & 5 of ESR-4266?

There is no "Save" button in Profis Engineering. Does it save automatically?

Please could you advise of a suitable product to seal a crack in an aquaduct. It needs to be non-toxic once cured. It will be installed in the dry.

When exporting from RISA Connection to Hilti I receive a message saying "Can't create file: C:\RISA\RISA Connection 12.0\Temp\"Filename".rcn". I am unable to export any connections to Hilti at this point.

Find the controlling tension or shear failure mode, and reduce utilization of this failure mode

ESR-2269 provides allowable tension and shear values for Hilti power-actuated fasteners driven into various base materials. Table 3 provides values for X-U and X-P PAF's driven into normal-weight concrete. Table 5 provides values for X-U and X-P PAF's driven into structural lightweight concrete with or without metal deck. Both...

Acid waste glass pipe 2" through cement block wall (2 hour rated) needs proper firestopping. Unable to locate specific UL system in Hilti Library

Avc for Concrete Edge failure direction seems to be calculating for a single anchor instead of for the group. Result is a severely over stressed condition for the group and for combined tension and shear. Single anchor capacity is fine when checked.

While evaluating anchors in Profis, I've noticed that the steel strength factor changes from 0.75 for longer embedment lengths to 1.2 for shorter embedment lengths and am looking for more information to understand why. If I could be pointed to the appropriate resource for explanation I would appreciate it.
