Groundwater was not encountered from the soil borings, so saturation shouldn't be an issue. Yes, the deadman anchor is a concrete block. I am not anticipating any uplift (buoyancy) from water in the soil since the soil is relatively dry. Not sure if it makes a difference, but the soil at the...

I am analyzing a deadman guy anchor for a telecommunications tower. The anchor has both significant uplift and lateral loads applied to it. For the lateral resistance, I've seen many calculations that account only for the passive pressure on the front face of the anchor. Because of the uplift...

I've copied the responses from Franklin Kurtz (AWWA Standards Engineer) and Stephen Meier (AWWA Standards Committee member) below. Mr. Meier's response is consistent with using the 1/3 stress increase for the entire equation. Mr. Kraus, See response below from Steve Meier of Tank Industry...

I wouldn't necessarily classify the stresses produced by the wind on a pedesphere as purely axial stresses, but rather stresses (tension/compression) that act in the axial direction as a result of bending. The lateral loads produce the fb stresses, and the gravity loads produce the fa stresses...

Section 3.3.3 of the AWWA D100-05 Standard states: "Members subject to stresses produced by wind or seismic loads may be proportioned for unit stresses one-third greater than those specified in Sec. 3.2 and Sec 3.4..." When looking at the combined stress Eq. 3-3 (fa/Fb + fb/Fb ≤ 1) for a...
