Structural Standards for Towers - TIA/EIA Wind Speed County Listing
(OP)
I'm using the TIA/EIA structural standard for steel antenna towers and antenna supporting structures. My question is in regards to determining the basic wind speed. I'm analyzing a monopole tower and the site is in Newport News, VA. Which is also the name of the county (Newport News) However, when looking up the applicable basic wind speed Newport News county is not listed. It seems as though the code is treating it as a city area not a county. What basic wind speed should be used in the analysis? The nearest county, other..?? Thanks for the help

The Newport News uniform building code says:
"Local Design Data:Wind Speed 90 MPH Continuos (BOCA); 110 MPH 3 Second Burst (ASCE-7)"

Be sure and check to see whether the structure is within 1500 ft of the shoreline or not. If so, then, you would need to upgrade to Exposure D.
