    Concrete block chimney

    Got it. I'll grout it all solid and bump-up everything accordingly. These are standard blocks, yes. The whole thing gets stone veneer.

    Concrete block chimney

    Why so tall? Architects! I had looked at it tying into this two-tiered porch which has a steel moment frame for lateral bracing of the chimney AND porch, but the columns I was using are "too big" because they'll conflict with the remote control roll-down screens. Like I said: architects :D...

    Concrete block chimney

    Hello all, I know this is probably a pain, but I have a 42' free-standing (abutts a two-story porch) chimney 32"x72"and am looking for design examples etc. Does anyone know of any good resources for designing partially grouted cmu boxes? MDG-7 has in-plane loaded shear walls, but they're fully...

    Strange Wood Framing | Concerns

    Solid block the joists max 7' o.c. Two rows would be nice, especially since the joists aren't blocked at the beam...just sittin' there. How these guys lay their subfloor without rolling joists and breaking their necks is beyond me sometimes.

    2012 IRC braced wall lines

    Edit: figure 602.10.1.1 seems to suggests that they should align, but I cannot find anywhere that specifically states that

    2012 IRC braced wall lines

    thread507-319099 The 4' offset is shown on one level. I don't see anywhere indicating that it has to stack over the one below. In fact, figure R602.10.8(2) suggests that the wall panels do not have to stack. The only mention of them having to stack that I can find is Section R602.10.2.1...

    Existing pipe below new slab on grade

    Probably depends more on the overdig for the pipe than the pipe itself

    insulating a structural slab

    Thanks for the reply. I think High 40 and it's cousins give a higher compressive strength (which we'll probably want), but not a higher R-value.

    insulating a structural slab

    Greetings all, I'm new to these forums although I've checked out a few threads over the years and the time has come for me to jump in. This isn't technically a structural question, but I think this is probably the place to get some good feedback. I have a project that involves a structural...
