I have what is probably a simple question but want to make sure I am right. When analyzing a continuous concrete beam that is uniformly loaded at the top would you take the effective depth from the bottom of the beam in checking one way shear at an internal support (location where you have...

I am a structural engineer working on a project with steel pipe driven piles. An issue has come up with the capacities of the steel pipe piles that were recommended by the geotechnical report. The geotechnical report made a recommendation of a pipe diameter and thickness (along with grade)...

Thanks for the posts and the link to the other discussion!

We have some conflicting opinions in the office and I am hoping to see what others in the engineering community think. The situation is a 100' x 100' warehouse with stick framing, wood trusses and a plywood ceiling. The assumption that has been made is that for the ends of the building where...

Everyone, Thanks for the responses. I reached out to Simpson as recommended and had some interesting conversations. In the old Simpson manuals they stated in the footnotes that capacities given were for an 11” beam and other depths needed to be calculated by the engineer. They excluded this...

I am designing a column cap plate and have encountered some confusion on NDS 3.4.3.3 in regards to uplift capacity. My situation is that I have a glulam beam supporting roof trusses and the base of the beam is attached to a glulam column with a column cap plate. In checking the shear stress in...

To give a little background into a situation where this has come up at our office in the past is when you have a 8 3/4" wide glulam beam being supported at the center of a continuous wall. The designs I have seen call for (6) 2x6 built up column framed into the wall to support the beam. This...

KootK thanks for the post I have actually gone to calling out the Simpson SDW screws for knee braces and built up columns where sheathing is not present. I also have the same opinion that the sheathing should preclude you from having to do the built-up fastening even though this is...

I am trying to determine if I use a built-up column in a wall to support a beam load do I need to fasten the individual plys together per NDS chapter 15.3. I am trying to determine if the 1/2" plywood sheathing on either side of the built-up member that has been noted to be fastened to each ply...
