The design wind speed shall be taken as the fol— lowing factor multiplied by the basic wind speed in. 27 Apr 2012 ASCE 7 Wind Load - How does ASCE 7-10 compare to ASCE 7-10 and some explanation of wind speeds. For each building risk category, an importance factor and wind-load factor are then applied to determine ultimate wind loads. Apr 27, 2012 ASCE 7 Wind Load - How does ASCE 7-10 compare to ASCE 7-10 and some explanation of wind speeds. 775 = 103 approx= 100mph which is what can be used in IRC/SBC-2 (this conversion is also necessary when ASCE 7-05 uses a single basic wind speed map. To determine wind-uplift resistance loads for a roof ASCE 7-10 and the 2012 IBC use ultimate wind speeds In ASCE 7-10 Table C26. • Wind speed maps in Chapter 6 are based 318) gives conversion factors for different MRIs. – Risk category III and IV (1700 9 Mar 2016 For example, for most of the same regions where a 90 mph wind speed was previously applied, in accordance with ASCE 7-10, the minimum velocity for Occupancy Category II is 115mph; for Category I (agricultural) it is 105mph; and for Categories III and IV (more than 300 people or essential occupancy) it is 120mph.
