Can someone out there point me in the direction of information on how to estimate the angle of uplift for deadman type concrete anchors (in this particular case, it's for analyzing the pullout resistance of anchors for a guyed communication tower). This angle is used to define the trapezoidal "wedge" of soil above a foundation which can be used to resist uplift forces. I've been scouring my books (and the internet) for information, but it seems there's very little information a can scare up. The only information I've seen says assume a 30 degree angle. I just can't believe that's universally true! My intuition tells me it should be related to the friction angle of the soil. Would "45-Phi/2" be a reasonable estimate? Any words of wisdom would be appreciated.
