RISA 3D Plate analysis for the win. This thing is nuts...Thanks for the input all!https://files.engineering.com/getfile.aspx?folder=fb0eaa3d-41a2-410b-a000-db184956fd2e&file=RISA-PLs.PNG
@WinelandV, I don't disagree. But this a good client that I can't pick and choose projects with so I have to help them thru it.
What you see is what you get (as currently designed); the forms are 10ga sheet steel panels that are going to be fabricated with all the in's and outs, tapers...
All, thanks for the thoughts and input.
@human909/civeng80: I like the cup analogy, but when I draw the FBD and run it in RISA with the pressures normal to the form I get an lateral instability so I must be missing something. If the two sides are not at the same angle (or height), the...
Hello all you concrete form experts!
First form design here for a valued client, so I can't say no. The forms will be fabricated from sheet steel, to pour a ~ 43-ft long concrete mass varying from 6'-10" high to 3'-4". See attached sketch cross section.
A couple of rookie questions:
-I think...
Jumping back in here, thanks for the dialog!
Galvanic rot sure looks like what I'm seeing in the field, however these are UNTREATED glulam with stainless steel fasteners, either of which would seem to eliminate that process. These beams are located INSIDE/INDOORS, just under the translucent...
Yikes, it's been a week....
Thanks for the input folks!
@dik, could be. I'm still not sure whether there was/is a roof leak, or if this is strickly from the interior moisture.
@lexpatrie, what you're seeing in the top picture is taking a picture of the roof system as high as I could get my...
Hello friends and experts!
A water park facility that I do some consulting work for has some issues with rot in a few glulam beams. The building structure is glulam framing with a transparent panel roof. The beams in question are horizonal girt members located in the eave of the roof, ~16-ft...
Thanks for the feedback all.
@Eng16080 I have not had enough time to really study NDS/AWC TR12 on this particular topic, but it seems that the fastener bending/bearing is generated due to the lateral load in pure shear and the bending/bearing occurs due to the side/main member interaction. To...
Hi All,
See attached; what do we do with case where a lag screw is loaded in shear and bending? Thinking of something like a kneewall clip or handrail bracket; does the load have to resolve to shear and tension only in the lag such that there has to be some component of compression on the...
@phamENG: We'll see; if they're not typical/shallow foundations as our proposal included a change order will be shipped....Not going to name names, but ding ding their office is in Elizabeth City (both firms that have proposed, actually).
@driftLimiter: Did you direct the geotech to provide a...
Thanks all!
@MTNClimber: IBC lists it as a requirement for SDC C-F. So if we're in SDC A/B (which we will be) no evaluation for liquefaction is required? Period? (@phamENG says so). It's seems that as the SDC gets worse the risk would for liquefaction would increase. But no risk at all at...
Hi all,
First project on the NC coast coming up; all my projects have been inland thus far. Project is in flood Zone AE with finish floor above the flood elevation, so at the beach but not underwater. Geotech asked if we needed a liquefaction potential analysis, to which I responded "huh??" I...
All, thanks for the feedback! Sorry for ghosting my own thread; I had several fires last week...
@RontheRedneck: I have seen/done the entire parapet being fabricated integral to the truss. Nice for the framers, I don't love the roof sheathing/diaphragm being held back so far from the shear...
