    European Wood, Grade C24

    Does anyone have experience with using wood framing with only a European grade, (C24) for use in the united states. No US grade has been assigned to it. It appears Europe just uses grade tiers, and no necessarily species for grouping their wood into properties. C24 relates to the Fb, ie C24...

    Long Span Wood Truss Roof/ Overall Stability

    As far as truss bracing goes, the contractor has been alerted of the issues and is taking them seriously. The truss supplier has conveyed this concern as well. Ther is currently language in the IBC concerning special inspections for trusses over 60' and so the bracing is suppose to be...

    Long Span Wood Truss Roof/ Overall Stability

    The roof diaphragm does not work with only the T&G plank so I added the plywood on top. The thickness of the plywood is a result of getting the right nail length and not having them poke through the exposed t&g plank. We are working on the bottom chord bracing; the Architect wants every other...

    Long Span Wood Truss Roof/ Overall Stability

    70' on a truck is bad, so is the road to the site. The GC says they can do it. For the roof deck we have 2" T&G plank that works for gravity loads, and 3/4" plywood on top for the diaphragm. Truss bracing is another challenge, because it is exposed the architect has their own ideas on what...

    Designing a brick veneer single angle

    For reasonable spans (up to 8' maybe a little more) I am pretty comfortable with the standard published angles sizes. When I have done longer spans I have added additional lateral support back to the wall/header. There is a schedule in this document for lintels up to 8'-0". I am not a fan of...

    Long Span Wood Truss Roof/ Overall Stability

    I have a structure where a few of the common discussion on here are converging on each other and I wanted to get opinions on my approach. • I have a long span (70’) mono sloped trusses with the top and bottom chords at different slopes. The trusses are bottom chord bearing and spaced at 7'-0"...

    Cantenary forces from batting cage nets

    Are you in an area where ice build-up on the net will add to the load?

    Plywood Floor Sheathing, staggered end joints.

    Thanks, we are working with a prefab floor panel system so we don't get the stagger.

    Plywood Floor Sheathing, staggered end joints.

    Most APA documents and some manufacturers indicate that end joints should be staggered when installing floor sheathing. The one exception that I can find is in the floor diaphragm capacity charts where they list six layout patterns including several with the end joints aligned. Is the...

    Slab on Metal Deck Diaphragm, Synthetic Fibers

    thanks for the input

    Slab on Metal Deck Diaphragm, Synthetic Fibers

    Using the Steel Deck Diaphragm Desing Manual, the concrete increases the shear strength of the deck alone, so both would be working together. The Manual goes on to say that "insulating concrete" helps as well and publishes values somewhere between the deck alone and structural concrete-filled deck.

    Slab on Metal Deck Diaphragm, Synthetic Fibers

    I am working on a project where the builder cannot get WWF for a composite slab on metal deck and they want to use a synthetic fiber mesh as a substitute. Setting other issues aside, I cannot seem to find anything about how this would influence the deck as a diaphragm. The SDI literature...

    LVL Beam Reinforced by Steel Plate

    You can try, but I think you will find it very difficult to develop the connection of the plate to the wood. The capacity of the screw in the wood will be too low.

    LVL Beam Reinforced by Steel Plate

    I would recommend bolting 11.5" vertical plate on one face, in sort of a flitch plate design. https://www.structuremag.org/wp-content/uploads/2014/09/D-From-Exp-Flitch-Plates-DeStefano-pac-5-10-071.pdf

    Net Allowable Bearing Pressure

    It is common for geotechnical reports to list Net Allowable Bearing Pressure for a recommendation for building foundations. When using these recommendations for standard site retaining walls, would an increase in the bearing pressure be acceptable? ie increase the bearing pressure by the depth...
