STRUCTURAL DESIGN
Figure 1609 Change to
read as shown:
Section 1609.1.4
Change to read as shown:
1609.1.4 Protection of
openings. In wind-borne debris regions, exterior
glazing that receives positive pressure in the lower 60 feet (18.3 m) in
buildings shall be assumed to be openings and the balance of glazed openings
in the rest of the building shall be assumed to be zero unless such glazing
that receives positive pressure is impact resistant or protected
with an impact resistant covering meeting the requirements of SSTD 12, ASTM E
1886 and ASTM E 1996, ANSI/DASMA 115 (for garage doors and rolling doors) or
Miami-Dade TAS 201, 202 and 203 or AAMA 506 referenced therein as follows:
(1 through 4
unchanged.)
5. Louvers. Louvers
protecting intake and exhaust
ventilation ducts not assumed to be open that are located within 30 feet (9144
mm) of grade shall meet requirements of the Large Missile Test.
Impact resistant
coverings shall be tested at 1.5 times the design pressure (positive or
negative) expressed in pounds per square feet as determined by the
Exceptions:
(Exception 1 unchanged)
2. Glazing Buildings
in occupancy Category I buildings as defined in Table 1604.5,
including production greenhouses that are occupied for growing plants on a
production or research basis, without public access shall be permitted to be
unprotected. as defined in Section 1602.
3.
Glazing in Occupancy Category II, III or IV buildings located over 60 feet (18
288 mm) above the ground and over 30 feet (9144 mm) above aggregate surface
roofs located within 1,500 feet (458 m) of the building shall be permitted to
be unprotected.
1609.2 Definitions. Change the text of the following
terms to read as shown:
WIND-BORNE
DEBRIS REGION.
1. Areas within one mile (1.6 km) of the coastal mean high
water line where the basic wind speed is 110 mph (49 m/s) or greater.
2. Areas where the basic wind speed is 120 mph (53 m/s) or
greater except from the eastern border of Franklin County to the
Florida-Alabama line where the region includes areas where design to 130mph or
higher wind speeds is required and areas within 1500 feet of the coastal mean
high water line.
Portions of
hurricane- prone regions that are within 1 mile (1.61 km) of the coastal mean
high water line where the basic wind speed is 110 mph (48 m/s) or greater; or
portions of hurricane-prone regions where the basic wind speed is 120 mph (53
m/s) or greater; or Hawaii.
CHAPTER
2, DEFINITIONS
Section R202 Revise the
following definitions to read as follows:
WIND-BORNE
DEBRIS REGION.
1. Areas within one mile (1.6 km) of the coastal mean high
water line where the basic wind speed is 110 mph (49 m/s) or greater.
2. Areas where the basic wind speed is 120 mph (53 m/s) or
greater except from the eastern border of Franklin County to the
Florida-Alabama line where the region includes areas where design to 130mph or
higher wind speeds is required and areas within 1500 feet of the coastal mean
high water line.
Portions of
hurricane- prone regions that are within 1 mile (1.61 km) of the coastal mean
high water line where the basic wind speed is 110 mph (48 m/s) or greater; or
portions of hurricane-prone regions where the basic wind speed is 120 mph (53
m/s) or greater; or Hawaii.
CHAPTER 3 BUILDING AND PLANNING
Figure R301.2(4) Change to
read as shown:
Change R301.2.1.2 to read as
follows:
R301.2.1.2 Protection of
openings Internal pressure. Windows in buildings
located in wind-borne debris regions shall have glazed openings protected from
wind-borne debris. or the building shall be
designed as a partially enclosed building in accordance with the Glazed opening
protection for wind-borne debris shall meet the requirements of the Large
Missile Test of ASTM E 1996 and of ASTM E 1886, SSTD 12, ANSI/DASMA 115
(for garage doors) or TAS 201, 202 and 203 or AAMA 506 referenced therein.
