SECTION 084113 - ALUMINUM-FRAMED ENTRANCES AND STOREFRONTS: continued
B. Delegated Design: Design aluminum-framed systems, including comprehensive engineering
analysis by a qualified professional engineer, using performance requirements and design
criteria indicated.
C. Structural Loads:
1. Wind Loads:
a. Basic Wind Speed: 150 mph.
b. Importance Factor: 1.1.
c. Exposure Category: D.
2. Seismic Loads: As listed on the Structural Drawings.
D. Deflection of Framing Members:
1. Deflection Normal to Wall Plane: Limited to edge of glass in a direction perpendicular to
glass plane shall not exceed L/175 of the glass edge length for each individual glazing lite
or an amount that restricts edge deflection of individual glazing lites to 3/4 inch,
whichever is less.
2. Deflection Parallel to Glazing Plane: Limited to L/360 of clear span or 1/8 inch,
whichever is smaller.
E. Structural-Test Performance: Provide aluminum-framed systems tested according to
ASTM E330 as follows:
1. When tested at positive and negative wind-load design pressures, systems do not
evidence deflection exceeding specified limits.
2. When tested at 150% of positive and negative wind-load design pressures, systems,
including anchorage, do not evidence material failures, structural distress, and permanent
deformation of main framing members exceeding 0.2% of span.
3. Test Durations: As required by design wind velocity, but not fewer than 10 seconds.
F. Windborne-Debris-Impact-Resistance Performance: Provide aluminum-framed systems that
pass missile-impact and cyclic-pressure tests when tested according to ASTM E1886 and
testing information in ASTM E1996.
1. Large-Missile Impact: For aluminum-framed systems located within 30 feet of grade.
G. Story Drift: Provide aluminum-framed systems that accommodate design displacement of
adjacent stories indicated.
1. Test Performance: Meet criteria for passing, based on building occupancy type, when
tested according to AAMA 501.4 at design displacement and 1.5 times design
displacement.
H. Air Infiltration: Provide aluminum-framed systems with maximum air leakage through fixed
glazing and framing areas of 0.06 cfm/sq. ft. of fixed wall area when tested according to
ASTM E283 at a minimum static-air-pressure difference of 1.57 lbf/sq. ft.
I. Water Penetration under Static Pressure: Provide aluminum-framed systems that do not
evidence water penetration through fixed glazing and framing areas when tested according to
ASTM E331 at a minimum static-air-pressure difference of 20% of positive wind-load design
pressure, but not less than 6.24 lbf/sq. ft.
J. Water Penetration under Dynamic Pressure: Provide aluminum-framed systems that do not
evidence water leakage through fixed glazing and framing areas when tested according to
AAMA 501.1 under dynamic pressure equal to 20% of positive wind-load design pressure, but
not less than 6.24 lbf/sq. ft.
1. Maximum Water Leakage: According to AAMA 501.1. Water leakage does not include
water controlled by flashing and gutters that is drained to exterior and water that cannot
damage adjacent materials or finishes.
K. Thermal Movements: Provide aluminum-framed systems that allow for thermal movements
resulting from the following maximum change (range) in ambient and surface temperatures.
