"Sec. 7-6.1. Aluminum Construction -- Minimum
Standards. Chapter 28 of the Southern Standard
Building Code, relating to Aluminum Construction IS

constructed or erected within the City. These
standards are cumulative of such standards set
forth in the Southern Standard Building Code.
(1) It is hereby found and determined that the
City of Sebastian lies within an area which requires
aluminum structures to have minimum design loads
that can resist 120 m.p.h. winds, as set forth on
the map located on page 12-14 of Chapter 12, Southern
Standard Building Code.
(2) All aluminum structures hereafter designed
and fabricated up to heights of thirty (30) feet,
must be designed to resist 120 m.p.h. winds.
Accordingly, the following minimum standards for
design are adopted:
(a) Basic velocity pressure -- 29 Pounds
Per Square Foot(P.S.F.).
(b) Open Structures (screen enclosures)
having 60% open area -- 10 P.S.F. times (x)
the direction factor and 1.3 in and out
for walls.
(c) Live Load -- 20 P.S.F. alloy 6063T6 =
FY2SK.S.I. 6063TS = 11.3K.S.I.
(d) Applied Loads. Using the above
established wind design, the following
may be allowed by the Building Official:
(1) No metal pans less than t = .032.
are considered herein.
.
e
e
(2) Metal combination of 6063T5 and
3003H16 may allow spans of five
(5) feet with 1.75 risers for twelve
(12) inch wide pans.
(3) Clear span of twelve (12) feet
with 1.75 inch risers using three (3)
inch riser interlocking.
(4) All screws must be S.M.S. minimum
#8 x 1/2 inch 4 inch C.C. Foundation
anchora~e against uplift. The
uplift orces calculated from wind
pressure shall not exceed 2/3 of
the dead load resisting moment. Base
anchors must be designed and installed
accordingly.
(e) Anchorage of structure to structure.
Aluminum pan roofs must be attached
directly to the structural members of the
structure, not to the facia board.
Anchorage of the roof to walls and columns
and of walls and columns to the foundation
shall be provided to resist overturning,
uplift, and sliding forces.
(3) Other designs may be accepted but drawings
must be accompanied by calculations and specifications
sealed by a professional designer.
(4) Three sets of plans (minimum 8!i'x 11") must
be submitted for review and approval by the Building
Official and shall contain the following:
(a) plot diagram
(b) SIze of structure
(c) type and size of beams
(d) type and size of columns
(e) bracing (where applicable)
(f) method of anchorage --
structure to structure, and
structure to foundation
(g) roof panels --
must indicate: clear span, t-factor
of material, spacing of anchors and
width of panels.
(5) The Building Official is hereby authorized
to prepare forms, engineering drawing with tables
and illustrations to assist applicants in applying
for and securing permits and to otherwise carry out
the intent of this section."
