We have vent piping going through a rated floor up through the roof. between the floor does the pipe need to be collared if it is 3?

I am attaching traffic signs to granite panels (hewn stone). The granite panels are just 2 or 3 thick and act as a facade for the structure behind. What type of anchor should I use that can grip the granite panel with very little embedment? I expect loads to be applied mostly in shear on the anchor. I assume that a concrete sc...

The published Hilti technical data on the Kwik-Flex screws list an allowable increase for both 1/4-14 and 1/4-20 screws of 1.44 when installed in steel with an Fu=65ksi or greater (highlighted on attached). The ESR 3332 report (Dril-Flex and Kwik-Flex) allows the same 1.44 increase for 1/4-14 screws into steel with an Fu = 65k...

The X-U 19 appears to be suitable for the beam flange thicknesses, so I wanted to see if there would be anything preventing us from approving this change?

I'm designing a post-installed anchor with the Anchoring to Concrete module. My anchor is a HAS Rod with HIT-HY200 adhesive. I'm confused why the module is showing a steel failure in tension when the worst case load combination is putting the anchor in compression? The net force on the anchor in this load combination does show...

Where or what Icon do I use to save the file. Or is saving as a template the only way to go.

I cannot enter the webinar.Technical.

Can you please let us know what is the allowable shear and tensile capacity of HILTI KH -EZ bolts in ksi?

EMT conduit was placed into the 2hr concrete deck with CAT-5 cables passing up into a wall above. I cannot find a system to match the (2) installations to the left, which the FLSO found acceptable. Please a...
