    Water leakage - external concrete overhangs interior ceiling

    Hello Ron, JAE, Thanks for your reviews and comments, time passes quickly but not quite there on this one yet. It took a few calls and e-mails but a local architect was employed and design drawings are due this week. The expected solution is just as you describe, just need to run it by the...

    Discontinuous stiffening of existing floor joist systems

    Hello boo1, Floor is level. No material was loaded over the tile. In fact, the stone for the fireplace isn't inside this home yet, it's out in his garage. I would also say the fireplace is very well supported and has 8 masonry columns around it's perimeter at this point and should not...

    Discontinuous stiffening of existing floor joist systems

    Hello Tmoose, Longest span is maybe 11 feet 6 inches. Shortest was just under 8 feet. Prior to the tile work, the owner had subbed some work to stiffen and cover the floor, doubling the joists (which we've seen was ineffective) and then putting down 1/2 inch cement board on top of his 3/4...

    Discontinuous stiffening of existing floor joist systems

    Hi boo1, JAE, Thanks a lot, I know what to do now, just need to wait for permission. I really appreciate your patience in reading and responding to the trickle of information.

    Water leakage - external concrete overhangs interior ceiling

    Hello JAE, Thank-you for the reply, I agree it may be a code violation and needs some research. I haven't sampled the concrete to see if any re-bar or other support is cantilevered over the interior ceiling such that not all the load is on the wood. I think anything is possible in this...

    Discontinuous stiffening of existing floor joist systems

    Hello boo1, Agreed. As observed, it's weak. The terminal ends are blocked, but none of the intermediate joints or overlaps is blocked. I've made the recommendation, but need to wait until the owner is comfortable or ready to risk the further stress/disruption of the tile in favor of...

    Discontinuous stiffening of existing floor joist systems

    Hello Boo1, Well . . . he doesn't want to nail additionally as his tile man has told him it will void all tile warranty due to impact and stress. From my inspection, many doubled joists are slightly cupped or angled with a noticeable gap where he may need to lag or bolt anyway, to draw...

    Water leakage - external concrete overhangs interior ceiling

    I'm working on an entry door water leakage problem into a basement. Home is 1997 design and construction. Builder is apparently out of business already. I need some design ideas about what to do to really fix this. The best description is to look at a picture, and a cross section: DoorPix...

    Discontinuous stiffening of existing floor joist systems

    Thanks for the replies, I did go and find/use a more standard FEA system to make some pictures that helped me explain to the owner his hoped-for effect and his likely outcome. And the box beam suggestion helped me illustrate the level of work he'd perform if more stiffness was truly his...

    Discontinuous stiffening of existing floor joist systems

    Greetings, I received a call yesterday (and I'm going to have a look later today) from a gentleman who has paid one firm to stiffen his existing joists underneath a single story kitchen by "doubling" them. And then paid another firm to add better subfloor and then ceramic tile over the top...
