GENERAL REQUIREMENTS
1) SCOPE: The prescriptive methods presented in this construction guide provide wind resistant de-
signs and construction details for various types of aluminum framed patio and accessory struc-
tures, lumber framed utility sheds, secondary covers for mobile home roofs, glass enclosures
(which may also be known as "sunrooms') and handrails and guards.
2) LIMITATIONS:
a. Provisions of this construction guide are intended to insure structural integrity for resisting
wind loads. Notes are provided at the beginning of each chapter specifying general param-
eters for each structure type. Where specific construction requirements are not given, ap-
propriate requirements of the Florida Building Code shall prevail.
gillred;bTtthe building ,official - "— ----" ""
3) Individual elementof a structure not in strict compliance with or addressed by this construction
guide may be engineered without requiring engineering for the entire structure, according to the
requirements of the Florida Building Code.
4) It is recognized that many alternatives are available to the designer for providing wind resistance.
This guide does not intend to prevent the use of such structurally equivalent alternative methods
(FBC 104.1.1).
5) MATERIAL SPECIFICATIONS:
a. Screen shall have a maximum density of 20X20 mesh with a maximum thread diameter of
.013".
b. Aluminum extrusions shall comply with ASTM B 221 and have a minimum wall thickness of
.040" (actual dimension without tolerance).
c. Aluminum sheet and plate shall comply with ASTM B 209.
d. Steel fasteners shall have a minimum ultimate tensile strength of 60 ksi and a maximum
ultimate tensile strength of 120 ksi and shall be coated for corrosion resistance.
e. For foundations, #5 bars shall be used and minimum concrete cover over reinforcing bars
shall be 3" where the concrete is cast against and permanently in contact with the earth;
or, 11/2" otherwise.
6) FABRICATION REQUIREMENTS:
7) INSTALLATION REQUIREMENTS:
a. Plumb and Level Tolerance: Members shall not deviate from level or plumb by more than
one half inch (1/2) in 10 feet.
b. Straightness Tolerance: Members shall not deviate from straight by more than one quarter
inch (1/a'1 in 10 feet.
GENERAL USER NOTES
1) Extrusions assumed to be alloy 600M and/or 6061T6 unless noted otherwise.
2) Tables which have numeric entries versus scalar variables (e.g. spans vs. load widths, or spans vs. wall
heights) may be interpolated.
AAF GUIDE TO ALUMINUM CONSTRUCTION IN HIGH WIND AREAS (2010 Edition) 2.0 H Page i
Chapter 2 - Screen Rooms
GENERAL NOTES: CHAPTER 2 — SCREEN ROOMS
1) Design Pressures from ASCE7 with Internal Pressure Coefficients (GCpi) determined
using Table 200, Importance Factor for Category I structures (0.87 for 100 mph
zone, 0.77 for all other zones).
2) Extrusion Alloy assumed to be 600M or 6061T6 unless noted otherwise
3) Concrete anchor terminology: Expansion Anchor / Sleeve Anchor / Wedge Anchors
are terms for various types of compression anchors. These different terms are used
synonymously in this publication.
4) "Approved Masonry Fastener" for connection to foundation must meet the following
specifications for 21/2" embedment into 2,500 psi (minimum) concrete:
a) 3/8" 0: allowable tension 1,055 #, shear 1,716 #
b) 1/4" 0: allowable tension 567 #, shear 394 #
5) For screen rooms constructed upon an approved lumber deck, 3/8" 0 Lag Screws
embedded by 3" into SYP lumber frame can be substituted for the approved masonry
fasteners specified in details C1 and C2.
6) Tables which have numeric entries versus scalar variables (e.g. spans vs. load
widths, or spans vs. wall heights) may be interpolated.
7) Maximum Mean Roof Height is 30ft
Allowable Roof Panel Spans (Table 201) are for Industry standard generic panel
products, approved equivalent products may be substituted based upon product
approval, in accordance with design pressures specified in Table 201.
Screen Rooms built adjacent to Mobile Homes (the so-called "4th wall" structure):
a) select beams, columns and foundations from Chapter 5 using type I or type II
as appropriate
b) provide lateral stability using cables from chapter 2 or K-Braces from Chapter
1, or connection to an appropriate shear resistant structure
Maximum roof slope 70 or 1'/2" in 12"
