[TowerTalk] Conversion of survivability wind ratings to EIA/TIA-222

[Jim Smith]

I understand that Appendix E of ASCE Manual 74 provides a method for 
conversion of wind speed ratings averaged over different periods of 
time.  I haven't been able to locate this manual in any of the local 
university or public libraries.  

I need to convert a 100 mph survivability rating into the equivalent EIA 
222 Basic Wind Speed.  Can anyone tell me how to do this?

TIA for your help
