Hello, I am looking to design embed plate and wall studs for a steel beam to concrete wall connection. Which is the best program to design the connection?

I have a question about anchors on metal deck. I only have 2" of concrete over the metal deck It doesn't appear I can get any type of anchor to work in this situation loads would be 8,400 lb-in of moment and 200 lb of shear at base connection to concrete. Seems like I am hitting a wall of anchors that can work in this situati...

Where can I find the size of the head of a particular Hilti anchor that I am designing?

On a marine bridge project concrete anchors and drilled and grouted rebar dowels will need to be performed by divers. Can HDA anchors be used for the concrete anchors? Can Hilti RA 500 system be used for the rebar dowels. What trades would do the installation or divers and what production rate can be anticipated. There will be...

I have one (1) bolt out of a four (4) bolt group that is tilted (out of plumb). They are Hilti Kwik bolts. Is there a reduction in the allowable due to the tilt?

We are needing a detail for a head of wall shaftwall condition. The shaft is a 2hr shaftwall and there are voids between the high flute and the top track. Is there a detail to avoid getting into the shaft to complete the rating from the double layer side of this shaft? For example possible stuffing the gap then spray/caulkin...

The floor slab is not required to be rated for our project, we only have to provide firestop at the curtainwall/slab edge condition per CBC 2019 section 714.5. The slab thickness is 6". Our curtain wall vertical mullion is spaced 48" o.c., but this Hilti design item 2B stated "locate mullions (vertical aluminum framing) min. ...

Do you have a firestop product that addresses a membrane penetration in a 1 hr wood framed wall.

Could one release the frictional engagement of the wedge by "unscrewing" the bolt and then pull the anchor out without damaging the concrete? This would be for a temporary installation.

The Hilti product technical guides list multiple min embedments/min hole depths for a given dia. of wedge anchor. For example, the TZ2 product guide, Table 1 under Installation parameters lists 1 1/2", 2", 2 1/2", 3 1/4" for the effective minimum embedment hef. Why are multiple values listed here? If I am looking for the minim...
