WebStandards are provided for minimum design loads (live, dead, snow, wind, rain, flood, ice, and earthquake as well as the required load combinations). The application of these loads and adherence to the serviceability criteria will enhance the protection of life and property. WebThe map below indicates the areas where high wind speeds dictate special design considerations. The current IRC code (IRC 2012) states that in regions where wind … Web1 compares the two wind speed maps from ASCE 7-10 (Figure 1-a) and ASCE 7-16 (Figure 1-b). While the old map had fewer ranges of wind speed across the United States, the new map divides it into more regions and specific wind speeds for each one. As examples, the previous wind speed for Category II for the West Coast was 110 mph, … how did animals come into existence
