1.2.2.2
Roof Live Loads
a.
Uniform Loads: Uniform roof live loads, including maintenance
traffic and construction loads, shall be determined and applied in
accordance with ASCE 7.
b.
Concentrated Loads: In addition to ASCE 7 roof live loads, a
minimum design concentrated load of 1335 N 300 pounds shall be
used to simulate a construction load on roof panels. The
concentrated load shall be applied at the panel midspan and shall
be resisted by a single standing seam metal roof panel, or a 610
mm 24 inches wide corrugated metal panel, assumed to be acting as
a beam. The undeformed shape of the panel shall be used to
determine the section properties.
1.2.2.3
Roof Snow Loads
The design roof snow loads, including effects of drifting, shall be
determined and applied in accordance with ASCE 7.
1.2.2.4
Wind Loads
Compute and apply wind pressures, ASCE 7.
Basic wind speed and multiplying
factors are as indicated.
1.2.2.5
Impact Loads
Impact loads due to [monorails] [cranes] [and] [_____] of [_____] magnitude
shall be applied as indicated in [MBMA MBSM] [AISC S335].
[1.2.2.6
Seismic Loads
**************************************************************************
NOTE: Procedures for determining and applying
seismic forces shall be in accordance with NAVFAC TI
809-04, or the Uniform Building Code.
**************************************************************************
As required for ground motion acceleration indicated.
]1.2.2.7
Collateral Loads
**************************************************************************
NOTE: Collateral loads include mechanical,
electrical, fire protection system.
**************************************************************************
[As indicated.]
[Collateral load of [_____] Pa pounds per square foot shall be applied to
the entire structure to account for the weight of additional permanent
materials other than the building system, such as sprinklers, mechanical
systems, electrical systems, hung partitions, and ceilings. This allowance
does not include the weight of hung equipment weighing 25 kg 50 pounds or
more. Equipment loads of 25 kg 50 pounds or more shall be shown on the
shop (detail) drawings and the structure (frame, purlins, girts) shall be
strengthened as required. The Contractor is responsible for providing the
building manufacturer the magnitude and approximate location of all
concentrated loads greater than 25 kgs 50 pounds before design of the
