Looking to put a 15'x20' roof deck atop an existing, older, 30'x40' building. The existing structure of the nearly flat roof does not meet today's building code. In order to leave the roof undisturbed, we planned to span the roof from side wall to side wall with small W shaped beams (the side...
Stop me if you've heard this before (but I'll need a picture to believe you). I'm reviewing the roof framing for a client with a 48' deep center hall colonial. The 10/12 pitch is formed with 11.88" LVL rafters at 16" on center, and they're tied at the top of the outside wall with continuous...
Ahhh contractors. I was brought onto a site where a 24' long W10x88 has been installed flush in a ceiling and the contractor has taken some liberties with pipe penetrations (see attached).
A quick beam analysis shows no real issues with the selection of the beam - it's effectively uniformly...
The 8'6" steel fluted column in these pictures is in service in the top floor of an old factory (1900+/-) building that was converted into condominiums in the early 1990s. It supports the roof structure of the building, but a client is hoping it's got the capacity to support one corner of a new...
I've got a 7.25" deep floor box into which I must shoehorn a steel beam. A W6x25 deflects too much on it's own, so I intend to build up the section with .25" x 4" plates welded to the top and bottom flanges.
The fabricator says a continuous fillet weld will cause heat damage the W6. Is that...
I've got a 24' wide house with a bearing wall dead center down the middle. StruCalc and Code say 2x10 floor joists (#2 DFL) at 16" are way more than fine for 30/20 loading at 12' span. Why then, does adding a second, equivalent span in StruCalc fail? I'd like to run continuous 24' joists over...
A builder here is putting up a 38' deep house is using 2x12 rafters (span = 19') and a non-structural ridge board. The frame will be tied together at the eaves with the appropriate thrust resisting connections. In my eyes, that's all good.
Changes get made in the field and now we've got two...
