I have a question regarding TIA-222-H Clause 2.6.9 & Table 2.2 How to determine the Gh & Kd in the below two cases of pole structures.a. Guyed pole structures.b. Pole supported with struts.For guyed pole structures, where the main structure consists of one tube. The structure may become rigid and additionally the forces in the pole depend on the direction of the wind relative to the directions of the guy cables.1. Can we use a guest factor of 0.85 and a wind probability factor of 0.85 (like guyed lattice tower)?2. Can we use the above factors for the case of a rooftop pole supported by struts? This wind will be used to check overturning stability over the square base. No anchors to the building roof.See figure 1 as example of pole with struts. Figure 2 as example for guyed pole.
