    What does that detail look like?

    Thats a good point, will mention this to the architect.

    decks

    IBC really has nothing on decks. For a multi story deck, is the preference to use full height column, and secure the ledger beam to the column, or notch the column? 4' x 8' decks up an apartment building.

    Footing capacity after 35 years

    Existing footing is 3' deep, 18" wide. Im trying make it one footing that takes the load, and if need be spread down the wall length a little.

    Footing capacity after 35 years

    Its a 54K load. With the eccentric load, the new footing would exceed the bearing pressure at the joint.

    Footing capacity after 35 years

    Im not forcing all of it onto the new one, just the left side. its a pretty even distribution under the combined footing, but unless I say the existing is spreading it out more (the 9'-6") ,then the combined is 2900psf at the footing on the left side. Maybe the question should be, do you think...

    Footing capacity after 35 years

    Would an existing wall footing (or really the soils) have additional capacity after 35 years from consolidation? I have a wall footing I want to add some load to. Current design pressure is 2000 allowable bearing. Its maybe got 900lbs/ft currently (including footing weight). I want to dowel...

    Strap bracing for roof purlin

    My thoughts was a roll of strapping, they can put in as much as they can. Doesn't need compressive strength, since a X

    Strap bracing for roof purlin

    Looking at options for bracing ZS purlins, and came up with strap bracing over bolted or welded angles, etc. Anyone ever done this? Would it make sense to call it out continuous, i.e. they just weave it in and out each space? Then lap at a joint as needed? Thanks

    Zee purlin fixity

    I saw that video. He mentioned different sized flanges, must be a proprietary shape.

    How to fix this?

    They couldnt slide the piece of plywood in the gap? Then make them use longer screws/nails, or a hanger that has different nail pattern.

    How to fix this?

    3/4" x 8" x 8" piece of plywood at each joist, screwed/nailed as needed. Fasten hanger properly thru that to packout.

    Zee purlin fixity

    Next question is lapping them, are they designed with one flange a bit smaller so they can lap flush, or are they just bolted together and squeezed?

    Zee purlin fixity

    I think I get that, not looking for fixed support, but a continuous beam via overlap.
