OP, did you use machine stress rated (MSR) grade lumber for your beam checks? I've seen some pole building designs that are specified to use MSR for the beams.

We have started showing two options on our plans. We usually show options for welding, screwing, or pneumatic pinning. EIT

Eng16080, Thank you for your response. As you suggested, I did use Eqs. (12.2-6a/b), but I don't think they are applicable due to being outside of the range of head diameters and side member thicknesses. Good call on checking the bearing perpendicular to grain. That check proved that I need...

I am designing the anchorage of a double 2x8 wood plate to concrete using a post-installed screw anchor. The applicable code is the 2018 IBC and the 2018 AWC NDS. I have the anchor design and the lateral load on the wood complete and there are no problems there. How do I calculate the...

I would suggest grouting all cells of the infill solid. It would add very little cost and would be stronger, more resistant to vandals, and more resistant to moisture intrusion. EIT

I wouldn't use sill seal either. You could install a piece of flashing over the ledger board and seal it into a reglet cut into the masonry. EIT

It looks to me like this is a moment connection between the beam and the column. The weld at the top flange of the beam is a complete joint penetration bevel weld with a backing plate. EIT

phamENG, thanks for your advice. Design Guide 15 answered my questions. I didn't even know to look there. What a great resource that is! EIT

All, I have a wide flange beam that I believe is a WF16x8.5 that would have been constructed in the early 1960s. What is the allowable stress for this beam if it was designed per the 5th edition of the AISC Manual? What is the allowable stress for this beam if it was designed per the 6th...

Thanks phamENG! That's what I needed, and more. EIT

Hello, I want to check the capacity of some existing steel columns that are TS7x7x3/8. The building was constructed in 1982. Does anyone have a reference that would specify the minimum yield stress of this shape for this time period? Thank you, EIT

Thank you all for the responses and the discussion. I appreciate the input! EIT

BA, Thanks for your response, indeed the 8" slab for that project was tied into the top of the wall. Retired13, Thanks for your response, I was specifically talking about the vertical rebar in the stem of the wall that crosses the plane at the top of the footing. I only have one set of bars...

Hello, I am designing a retaining wall and the concrete needs to be designed according to ACI 318-14. Please refer to the attachment for a general sense of what I am talking about. However, my specific design has different dimensions and loading than shown in the attachment. The vertical...

Ok, thank you both for the quick responses! RPMG, thanks for the simple sketch. That makes it look so simple and, in my opinion, is hard to argue with. EIT
