    intresting brick lintel installation idea to existing

    I guess my problem with it is that I've never had a problem putting lintels into existing walls for new openings. I suppose if you've never had the opportunity to work with old guys who've been around, and then eventually become one of the old guys who's been around, you need someone to do some...

    Non engineer asking: where in geotech does it say i need perimeter drainage

    Sorry, forgot one comment re hole location: it depends if you are collecting or distributing. I don't want to disagree with concretemasonry but I wouldn't collect with pipes intended for distributing, which is what pipes with holes in one half are for. Use fully perforated pipe for foundation...

    Non engineer asking: where in geotech does it say i need perimeter drainage

    I have to say, I have never heard of anyone building a basement in our area without exterior perimeter drainage in more than 75 years, maybe 100. It is simple, easy & cheap to do when you are building, and the opposite of that next year when you have problems. And if you do it without...

    Walkout basement...concrete or wood wall?

    Your concrete guys are not going to pour a wall 14' high in one lift, especially if they typically only do house basements. If the wall is prohibitively expensive you can keep the footings the same level throughout, & insulate them for frost. Far easier to design and build, and costs quite a...

    Bolts in dual dimensioned drawing

    I'm in Canada where our official system is metric, most people think in imperial, and we build in a bit of both. As briancpotter said, the bolts are either metric or imperial & there is no calling one by the other's name. You specify the bolts & that's that.

    Gaming floor live load

    As I just said in another post, look at physical realities. 100 psf is an incredibly heavy load to impose on a floor that must have circulation space, gaming tables, chairs, etc. If you want to do it with people, you need a 200lb man in every single 2'x1' space in the room. How did they get in...

    Impact (Dancing) Loading on Timber Design

    Why is it so common to ignore physical realities? The room is 15x20,x 40psf = 12,000lb. 200lb/person = 60 people & we're asked if it's okay for 20? Put 60 200 lb. people in a 15X20 room & I want to see them twist & shout, never mind putting 150 people (100psf) in that room. Give your head a...

    Chemical timber fastening epoxy???

    Any hole parallel to the grain will most often get smaller, not larger if the wood dries, depending upon its location with respect to growth rings. Also, the wood in question is existing in its existing service conditions and is unlikely to change much. Trust me, 35 years of experience with...

    multi-ply continous wood beam fastening

    The fastening of plies has an awful lot to do with the way the beam is loaded. If a beam is loaded from one face, the fasteners must transfer the load to the other plies. If the beam is loaded from the top, the fasteners must simply hold the plies together, providing lateral restraint if an...

    Factor of Safety for Uplift -Tension Piles

    Okay, except that DL is 1.25, not 1.5, so we're still cheated.

    Stone Adhesive

    My point was that I can buy stone sliced to 1/2 or 3/4" thick just like a tile and possibly lighter than ceramic of the same thickness, & if I glue that to a wall, adhesive is perfectly acceptable. If I decide to glue 4" thick veneer stone to a soffit, I deserve whichever pieces hit me and...

    Factor of Safety for Uplift -Tension Piles

    I have always (okay, maybe not always, but usually) used an allowance for dead load for design instead of trying to figure out an actual, just as SteelPE says: X psf DL for whatever the area is, and X live load, and do your design. Then when it comes to uplift, figure out the real weight of...

    Stone Adhesive

    As Ron says, the configuration (weight, orientation, etc.) has a lot to do with the answer to the initial question. I wouldn't count on adhesive to glue a thick stone soffit in place, but I have used it for a thin veneer on walls many times. What is the difference between stone & ceramic tile...

    Reinforcing an existing LVL-Flitch Beam

    You jack it to take the weight off while the new connections and members are installed, then remove the jacks to load them. Without jacking, the remedial work does not do anything until the beam deflects further. Whether or not you can remove an existing unsightly deflection is a different...

    Things to consider when building gymnasium on ground floor

    Many years ago, I went to a highschool with the cafeteria & kitchen under the gymnasium. As a matter of fact, my father built the building about 2 years before I went there. The floor was wood: hardwood finish on heavy timber deck on glulam beams, somewhat bigger than what is discussed here; I...
