Plate yield lines

[jshapton]

I have a steel plate with an infinite length spanning a distance &quot;b&quot; with a concentrated load @ b/2. Is the yield line for this plate an &quot;>I<&quot; with the &quot;I&quot; running parallel to the supports? I am trying to establish an effective width other than assuming a 45 degree distribution (effective width = &quot;b&quot.

Why you don't try both and pick the smaller. The yield line method is based on the lower bound theorem, thus any solution will be larger than the exact solution.

jshapton,

You are jumping the circular failure, or just a poligonal aproximation. The size of the failure could be smaller than the distance &quot;b&quot;.
