Anchor Bearing Plate Thickness
Anchor Bearing Plate Thickness
(OP)
I am currently working on designing a size of anchor bearing plate for 45 ft. high anchored soldier pile wall and want to get your advice on it. Initially I simply tried with a simple beam model to design the thickness of the plate, but after finishing the calcs I thought that the number I came up with was too high. Now I am trying to use one of formulars for flat plate in Roark's stress strain formular book and not so sure which case in the book I should use. Any thoughts on this?

There are many variations on this setup, so you will need to know the span, diameter of the center hole and diameter of the anchor head (these will vary greatly depending on whether you use strand or bar anchors).
Another factor to consider is whether you design around the anchor design load or test load (typically 1.33*DL). This will depend on the type of jack chair you use while testing. You also may be allowed to use a 20% overstress in the steel depending on if this is a temporary or permanent wall.
Many of these details vary by contractor preference, which is why most of them design their own work to fit with their methods.

I would use Formula 2k if I had a bearing plate sitting on concrete (as for dam tiedown anchors) and the hole in the concrete has a larger diameter than the diameter of the anchor head.
Comments?

Talk with your anchor tendon manufacturer. Many are happy to provide this kind of support (and have engineers on staff to do the work) provided that you have bought your system components from them.
We routinely use (for example) spreadsheets provided from DYWIDAG Systems International for the design of bearing plates with DYWIDAG bar and strand tendon anchors.
