Also search for Boussinesq Equation.
AASHTO adopts a form of the Boussinesq Equation for their adjacent surcharge formulas.
Usually try to go for cast-in anchors but shy away from proprietary anchors so just a standard hex head bolt checked using ACI/NDS.
I also like to get that continuous top bar on the outside face of the anchor, feels better having it in the knuckle of the bar bend and also on the free edge side...
See lots of bug posts in the LibreOffice bugzilla regarding this but nothing stands out as a cause:
here were the most common issues I found:
The sheet was not auto-calculating after the paste operations so it only looked like the value instead of the formula was pasted. Force a sheet re-calc...
I tend to use mostly mainstream packages like Numpy and Scipy. It's a balance though one which I struggle with constantly wanting to figure things out on my own and write the code myself vs finding something pre built to utilize.
If you’re mostly after load tracing then woodworks concept mode is passable. Autodesk Robot added in a load take down analysis in 2023 which functions ok within it’s limits, I’d say if you have robot already worth giving it a try.
@Tygra:
"...and I will do what you say."
Please don't just do that because I said to. Figure out for yourself what the function of the walls is intended to be. If they are intended to be load bearing then keep them, if they are masonry or concrete frame the short beam to the wall end if they...
What does the floor plan look like, anyway to justify a 3-sided diaphragm?
Anything new I'd probably add in board of the brick and carry down to a new foundation, unlikely you'll find any products for anchoring to the top of an existing brick wall.
Interestingly seems the previous iteration of this problem had the correct solution: eng-tips thread
I think this was meant as a “gotcha” problem and perhaps it “got” the solution writer this go around.
I would argue the proposed solution is incorrect for the shown configuration, the critical bend plane is actually in the vertical leg. The load configuration shown will cause the angle heel to pull away from the wall and the vertical leg will bend about the anchor.
So the critical value for P...

"I'm a little rusty on my integration, but I thought all of the constants turned out to be zero."
you are correct I did not download the earlier PDF and thought the derivation was for the Sin load applied partially to a span not to a full simple span.
Some Observations:
1. Your derivations for a sinusoidal load are all missing the integration constants which would be solved by applying the relevant boundary conditions.
2. I can vouch for the SkyCiv analysis being correct for the inputs noted in the printed software output.
3. Is your "beam"...
You had a wall and a beam in the same location in your model. The software was applying a portion of the distributed load directly to the wall panel and the remainder to the steel beam which is why when you looked at the beam the load stepped down where the wall co-existed.
You said you deleted...
Greg:
Interestingly enough it seems this structure is sensitive to the axial rigidity of the members when the load is applied to the corner nodes only.
Models:
25.8kN applied to upper left node 25.8kN applied as opposing forces to upper corner nodes
25.8kN applied to...
"I am surprised that the axial stiffness made even that much difference in FX."
To clarify my hand calc. did not include axial stiffness and in the software I used large members to make the impact of the axial deformation negligible I also disabled shear deformations.
