I am designing an unheated enclosed single-story storage type building that is 500 ft x 30 ft.
In this type of building the metal stud walls that frame the building are bearing on the slab-on-grade and and also act as shear walls.
Would it be wise to include transverse expansion joints in the...
She said it was to save on cost since treating the full height would be too expensive. The architect has been very specific/strict on what we can do since they have a lot of past pole barn projects they can point to that are still standing. This is our first time designing this type of building...
I designed for my boss a wood pole barn building (16 ft eave height) for an outside architect. We specified the (4) 2x8 wood posts to be treated for the whole length. These posts are embedded 6 ft down in concrete so we assumed a fixed base in the design, which is why we say to treat the whole...
The projects I typically work on are in warm climates where frost depth is not too much of an issue (my company generally thickens the concrete mat down to frost depth). We have a project now in New England and frost depth is apparently 4-5 ft up there.
What is typically done to design an...
I am a structural engineer and am working on a switchgear enclosure foundation. The electrical engineer is also requiring us to provide a design for a concrete encased duct bank for four 5" schedule 40 conduits in a 2 x 2 configuration and is requiring that it be reinforced. I generally had...
I am currently developing a framing section and have a question on a light gauge steel connection. What would the best way to support the end of the low roof joist shown below? Right now I'm showing a skewed track connected to the outside face of the stud wall to receive the sloped roof joists...
I've got a 1000S200-68 light gauge steel member bearing on top of a 6" stud wall as shown below. What is the typical approach in detailing the sloped condition? Would you miter the studs and bend the top wall track to match the slope of the roof joists? Or would you keep it level like below and...
I am somewhat familiar with designing concrete tanks based on the PCA design method for rectangular and circular tanks.
For tanks shaped like below, I am guessing you would use a combination of both methods? Not exactly sure how to approach this one.
They are saying that there is nothing in the NCMA literature that suggests wire tying will gain any strength (almost verbatim). To me, they are saying the rebar positioners would act as the tie to splice/lap the vertical bars. I guess it would work if you tie the bars to the positioner itself...
In our specs we say to use rebar positioners to center the bars in the CMU walls and also to use wire ties for contact splices. I got an RFI for a project out to bid saying that rebar positioners are designed to space the bars so they do not contact each other to allow grout to flow between the...
I am working on a project with pitched gable roof framed with a long span light gauge roof truss. The trusses are bearing on the CMU walls, where there are any and also on steel beams. The CMU walls will terminate at the bottom chords of the trusses.
I do not have any experience with this kind...
I was reading NCMA TEK 17-1D to figure out if I can assume arching for the design of a lintel in a masonry wall.
I seem to be able to check off all of the required conditions except maybe the one about having "sufficient masonry on each side of the opening to resist lateral thrust from the...
EZBuilding, would you locate the anchor where I show it in green below (in the 4"± depth of concrete above the top flange)? I don't believe the magnitude of the load will be very high.
BAretired,
The partition wall is 6" metal stud with height of maybe 14 ft.
It is laterally supported by the floor above.
Since it was the architect that suggested the angle idea initially, I am assuming it does not have to be fire rated.
The guy on site just told me there is about 4" of concrete cover above the flange so if we wanted to pump grout underneath the flange, that wouldn't leave much room to anchor the vertical leg of the angle to the existing concrete, as shown in your first markup.
Another thought I just had is...
retired13, what if I increase the gap between the vertical leg and the existing beam to say, 1 inch? The bottom gap would then need to be sealed somehow for the grout to be pumped in.
Thank you all of your responses. Very helpful to get different perspectives. I've taken different aspects and came up with the following. Can someone give me a sanity check that this is a viable solution? It is basically a two angle solution connecting to the existing steel while trying to...
So I've got an existing concrete encased steel beam (red in the image). An additional 8" needs to be added to extend the floor to support a non-loading bearing partition wall. One suggestion was to attach an 8" angle (in blue) to the side of the existing concrete. How would one go about making a...
