Afternoon all,
I am working on a renovation of an existing historic brick building. It's over 100 years old and I'm just not sure how to approach the brick condition/ verifying that the brick can handle the additional loads. The extent of the renovation as far is the brick is concerned are some embeds using the Hilti SC sleeves, these embeds support some floor framing that frames out a new elevator shaft opening. I'm doing the design of the embeds in HILTI and can get them to work but there are a ton of assumptions in the footnotes in the product catalog, one of them being that "minimum masonry strength of 3,000 psi", so my PM has asked that we provide proof loading values to cover ourselves and verify the brick capacity. I've looked through the IEBC appendix where it discusses this but I'm still a little fuzzy on the approach. I've never been involved or worked on proof testing before, how have you all approached this when it comes to older brick masonry?
I feel like I'm starting to go in circles a bit so any direction/help would be greatly appreciated. Thanks.
