Does this have to be steel? With such a small load, you could use a (wood) 2x6. It's readily available and relatively light. Maybe not a better solution than Unistrut, but perhaps a reasonable option.
I'd probably go with something like this:
So, sister a new 2x piece to the side of each 2x10. If this doesn't work for the required load, then go with the same detail for each side. There will be a little interference between the new pieces and the LUS210. If that matters, you can provide a...
I just don't understand why one of the most brilliant minds here would subject themself to a client like this who clearly doesn't value engineering at all.
It was more a hypothesis than anything, but my thinking is that if the connection "failing" means that it deforms some small amount, then at that point the knee brace "support" suddenly becomes less stiff and more of the beam's load goes directly to the post. The thinking is that the...
Can you clarify what this means? I assume you have two frame lines in each direction, meaning a total of 4 posts, 4 beams, and 8 knee braces. Is this correct? If so, does that mean a total of 1k lateral load on the structure, split between the 2 frame lines?
Roughly, how far do the knee...
Another potential problem with the double shear plate is that it might not provide adequate ductility to meet the classification of a simple shear connection per AISC Table 10-1. In that case, the structural model (and member design) would need to account for moment being transferred at the...
I agree. (I wasn't meaning that the joists had to be connected directly to the steel beam.) I would probably use shop holes and bolts rather than welded studs. I called for welded studs on a recent project for this exact purpose and was told it's much more costly than drilling the holes and...
How is a single plate being used to make this connection, whereas the detail shown at the top has a total of 3 plates?
If you're suggesting to field weld the T to the face of the column, I think that would be more labor/$$$ than keeping the single shear plate with bolts.
I'd consider it bad practice to not connect the joists to the beam. If you were going to do this, though, then you should design the steel beam as laterally unbraced for its full length. This will likely result in a much larger beam section, and any savings in not providing connections will...
Not sure this makes sense. Certainly, I've never seen this type of connection. In cases where a single angle doesn't work, it's common to use a double angle connection instead.
On most projects, I rely on both connection types. I wouldn't necessarily consider one type better, at least based on the work that I do, which is mostly residential and where beam sizes are generally not excessively deep.
I'll often have a steel beam supported by intermediate columns. I use...
I don't use knee braces very often, but I posted here a little over a year ago about their design: https://www.eng-tips.com/threads/pre-fab-steel-knee-brackets-for-6x6-deck-posts.516562/post-8969757.
It's a bit of a rambling comment, but I concluded that for most wood knee brace connections...
