Wind speed hinit in ASCE 7-10 corresponds to the rounded value franc the following <br />relationship: V ASCE7-10 = V ASCE7.05 x (1.6)"2. <br />2. See ASCE 7 for detailed in-forniation on glazed opening protection and considerations for <br />new treatment of Risk Category under ASCE 7-10. Both ASCE 7-05 and ASCE 7-10 contain <br />an exception to glazed opening protection based on height above ground and proximity to <br />aggregate surfaced roofs. <br />Under ASCE 7-10 provisions for glazed opening protection, wind speed maps associated with <br />Risk Category 11 are used for all Risk Category It buildings and structures and Risk Category III <br />buildings except for health care facilities. Wind speed maps for Risk Category III and IV are <br />used for Risk Category III health care facilities and Risk Category IV buildings and structures. <br />The combined effect of map changes and revised wind speed triggers is that there are location - <br />and building -specific differences between ASCE 7-10, and ASCE 7-05 requirements. These <br />differences can be significant. For example, sorric locations and building types may require <br />glazed opening protection tinder ASCE 7-10 where opening protection was not previously <br />required under ASCE 7-05. <br />ASCE 7-10 Wind Provisions 8 LinelCoulbourne <br />
