Load/Span Tables are based on full
scale tests that consider three design parameters:
- Critical bending moment at actual
panel failure
- Flexural stiffness
- Pullover force per fastener of the
panel section.
Table values are based upon:
- Roofing: Deflection l/60, FOS
2.5+, 1.88-
- Siding: Deflection L/30 FOS
1.88
|
|
|
|
|
The load/span tables shown in this
Guide are derived large scale tests using full panels to simulate actual service
conditions (at a reference temperature of 77° F). These tests include two span vacuum box
test and three point load tests.
Each span shown in the load/span tables represents the most conservative span derived when
the panel is assessed using the following parameters:
Design Parameters
- Critical bending moment at actual
panel failure;
- Flexural stiffness factor, EI, (where
E is the flexural
modulus of elasticity and I is the moment of inertia of
the panel section); and
- Pullover force resistance per
fastener.

|
The load/span tables shown in this
Guide are developed using the following maximum deflections limits and Factors of Safety
(FOS), unless otherwise noted:
Panel Roofing:
Positive Loads: Deflection: L/60, FOS:2.5
Negative Loads: Deflection: L/60, FOS: 1.88
Panel Siding:
Wind Loads: Deflection: L/30, FOS:1.88
Roof Deck:
Dead + Live Loads: Deflection: L/180, FOS:2.5 Uplift Loads: Deflection: L/18000, FOS:1.88
The load/span tables are to be used as a guide only as specific environmental conditions
are not considered.
Specific applications should be verified by a registered
Professional Engineer. |
