We have a CMU wall with a lateral brace L angle at the top of the wall on one side. On the other side of the wall we have a lateral brace L angle, however this one is attached to an open web steel joist. Is there a firestopping assembly solution for the top side of the cmu wall where the steel joist is located.
The area of concern is highlighted in a red circle in the attached pdf.
Hi Ruddy - thanks for using AskHilti! This one looks like it's going to need an Engineering Judgment. The biggest challenge I'm seeing from your detail though is what the accessibility is going to look like in the head of wall joint.
We are proud to announce the launch of the HILTI CONSTRUCTION PLATFORM (HCP), our company’s new engineering service website. This platform will be the home for all of your Fire Protection Design needs. Instead of emailing a PDF form for a request, the platform enables you to create new Engineering Judgment (EJ) requests, submit revisions to previously completed EJs or connect with an FPE on a question. HCP also enables you to track the status of your request.
You can find more information on how to access this new platform here: http://www.hilti.com/ej (US) or http://www.hilti.ca/ej (Canada.) If you have any questions or require assistance navigating the platform, please call Customer Service for help at 1-800-879-8000 (US) or 1-800-363-4458 (Canada.)
Thanks!
Nate Crawford - Lead FPE
