/ = importance factor. As discussed in SEc. 2.4, the concept behind the
importance factor is that certain structures should be diseigned for higher force
levels than ordinary structures. Except for the default value of 1.0, note that
the importance factors for snow, wind, and seismic forces are not equal.
the importance factorⅠfor wind load is provided in ASCE 7 Table 6-1, as a
function of the occupancy category(introced in Sec2.4). The occupancy cat-
egories are found in ASCE 7 Table 1-1 or IBC Table 1604.5. This book uses the
ASCE 7 tables; hoever, the reader is reminded that the IBC table must be
checked when conformance with the IBC is required.
standard occupancy structures will fall under Occupancy Category Ⅱand have
a wind importance factor Ⅰof 1.0. Structures with high numbers of occupants or
housing essential faclities or hazardous materils will fall into Occupancy
Categories Ⅲ or Ⅳ and have a wind importance factor Ⅰof 1.15. This value of Ⅰ
was selected because it represents an approximate conversion of the 50-year wind-
speed recurrence interval in ASCE 7 Fig. 6-1 to a 100-year recurrence interval.

楼主用前需要核对一下的，我打完就发了，不过应该没什么错的，以防万一哈。

我觉得你太懒了。自己不动手干嘛靠别人
