We have found our selves an unusual condition that the building inspector is taking issue to. Off set walls using TGI floor joists. 1 hr construction We have attached a photo and two drawings illustration the condition.. Please advise.

How can we calculate the European designed corrugated Canned anchors? Can Hilti supply this type of anchoring system.

What does the detail for the anchor/nut that is torqued against the concrete look like? Do you just need to specify a washer or is an additional plate necessary? How do I specify a selected Hilti anchor in the catalog for having a standoff distance for with the extra nuts and washers on the anchor bolts?

During the injection of epoxy, a piston/plug fell into the hole, resulting in epoxy filling the space above it and a void below. Is it possible to drill through the cured epoxy (HIT 200A) to remove the piston/plug and then refill the hole with HIT 200A to properly abandon it? Given that the epoxy has a compressive strength of ...

Profis still does not have pre-built load combinations to where we would input load cases only and those would distributed into an applicable load combination. Instead it asks us to input already factored loads. The question is what factored loads? LRFD combination factored loads or ASD? What design properties is Hilti produc...

I am designing a connection, using Hilti Profis and I was getting that the connection was failing so I checked my design against the value in the tables and I was getting that the anchor bolt should pass. I have included the results from my analysis and how I typically use the Hilti tables as an attachment. Am I missing a fact...

I have a transition between a 2-hr shaft wall (1st floor) and a 1-hr (2nd floor) exterior wall and need to know how to provide a fire stopping condition between them. Would a fire retardant wood blocking (see clouded area) be sufficient or should I use another type of firestopping material?

We have a project with high roof deflections that are also supporting/hanging misc infrastructure from the roof deck. At the worst case, the roof may deflect up to 4 (+/-2 down). If there are any fire stopping systems for piping, ducts or other infrastructure can you let us know if any exist by Hilti?

Why is the software adding up the plastic moment of two different anchors which areas do not overlap when calculating the demand? When looking at the weak axis bending due to tension, the program seems to be adding up two plastic moments for distribution areas that do not overlap. The only reasoning I can see behind that, woul...
