This report presents a damage potential scale for storm winds other than tornadoes and hurricanes derived from storm damage reports in the NOAA monthly publication Storm Data by using threshold values in the scale. Wind design criteria are proposed for the design of the Army functional system of field shelters. An inherent advantage seen for the proposed criteria is that they are derived from storm winds most likely to be experienced in the field. Since the scale is based on storm data from a region known for its tornado activity, thunderstorm severity and cold front intensity and squall line passages, the wind criteria probably pose as severe design conditions as might be expected in any operational area in the world. Furthermore, normal engineering practices are believed to have the flexibility to allow design changes for various regions of the world, the criticalness of the shelter function, and for different service live expectancies.
