Is it persmissable to attach a metal stud directly to a beam without a clip and then fireproof the wide flange and the metal stud together? We cannot find a detail that allows this attachment. The wall under the beam is not fire rated.

Hilti HDI and HD-L allowed for seismic per IBC seismic cat D?

For a 1/2 KB TZ2 Anchor with 2-1/2 effective embedment, the minimum concrete thickness is stated as 5. For a concrete deck, the requirement is to keep the hole minimum 5/8 from the surface. If an anchor is installed from the top into a deck which is 4-1/2 thick in addition to 3 steel deck (total 7-1/2) can the 2-1/2 eff. em...

I'm attempting to design attachment of cold-formed metal track to the top of concrete over metal deck using X-U PAFs. The substrate in this project is 2-1/2 NW Concrete over 1-1/2 20ga composite metal deck (4 total thickness of system). I've found information that requires concrete thickness to be minimum 3x the embed depth o...

We installed 1-1/4 to 1-1/2 EMT conduit within the wall, extending down to the floor below. This conduit will serve as a chase for data cabling connected to poke-through floor boxes, with both ends stubbing out from the wall above and the floor below. Is there a fire-stopping detail available or an EJ alternative that illustra...

Do you have any webinars or information relative to when F & T ratings are required and what are the approved details. I'm interested in conduit, piping, and buss penetrations.

Please refer to the photo. Anchor is marked as 4 1/2 length and as 4 cross hairs. Is this an anchor you recognize? Was unable to match the head mark, the 4 cross hair dashes, with the available documentation. Thank You,

The referenced code sections seem to allow through penetrations of rated walls and horizontal assemblies without an approved firestop system provided that: 1) The penetrating items are steel, ferrous, or copper pipes, tubes, or conduits and 2) The material used to fill the annular space shall prevent the passage of flame and h...

We are working on an interior fitout of a space within a high rise building and have found a hole at the edge of slab through the firestopping and smoke seal. The hole is about 3 long and carries through to the floor below. Can you suggest a product that would easily fill this hole and will meet 2 hour fire and smoke separat...
