Is it ok to attach a strutting beam in a add-on garage to the chimney chase? I’m thinking not, chimney chases are not a structural component of the home.
Terry, I’ve never heard the term “Strutting Beam”. What’s your source for that term?
Are you asking if a structural support beam can be safely secured to a brick chimney? If so, I’d guess that would depend on the magnitude of the load. I can’t tell from your photos what kind of load those beams carry and it appears that at least part of the horizontal beam (I assume that’s the one you’re referring to) bears directly on brick instead of being attached to it by fasteners. In fact, I don’t see any fasteners connecting the beam to brick.
One of several variations.
