DESIGN ANALYSIS
**************************************************************************
NOTE: When the SSSMR system is a component of a
metal building system, the loading criteria
specified in Section 13120 PREENGINEERED METAL
BUILDINGS or Section 13121 METAL BUILDING SYSTEMS
(MINOR REQUIREMENTS), will apply and these
paragraphs will be coordinated accordingly. A
reference to the pertinent Section will be made for
design conditions, and applicable paragraphs of
Section 13120 PREENGINEERED METAL BUILDINGS, or
Section 13121 METAL BUILDING SYSTEMS (MINOR
REQUIREMENTS) will be edited accordingly.
**************************************************************************
The design of the SSSMR system shall be provided by the Contractor as a
complete system. Members and connections not indicated on the drawings
shall be designed by the Contractor. Roof panels, components, transitions,
accessories, and assemblies shall be supplied by the same roofing system
manufacturer.
1.4.1
Design Criteria
**************************************************************************
NOTE: Loads and load combinations will be in
accordance with ASCE 7. The designer will provide
loading diagrams/tables on the contract drawings,
plus dimensions of edge, eave, ridge and corner
zones.
**************************************************************************
Design criteria shall be in accordance with ASCE 7.
1.4.2
Dead Loads
The dead load shall be the weight of the SSSMR system. Collateral loads
such as sprinklers, mechanical and electrical systems, and ceilings shall
not be attached to the panels.
1.4.3
Live Loads
1.4.3.1
Concentrated Loads
The panels and anchor clips shall be capable of supporting a 1335 N 300
pound concentrated load. The concentrated load shall be applied at the
panel midspan and will be resisted by a single standing seam metal roof
panel assumed to be acting as a beam. The undeformed shape of the panel
shall be used to determine the section properties.
1.4.3.2
Uniform Loads
**************************************************************************
NOTE: The minimum roof live load will be not less
than 960 Pa (20 psf).
**************************************************************************
The panels and concealed anchor clips shall be capable of supporting a
minimum uniform live load of [960] [_____] Pa [20] [_____] psf.
