Allowable Concentrated Load (C):
Values indicated in the rows labeled "C" are the lowest of the (1)
maximum allowable concentrated load considering channel flexure (Figure II below),
with both channels effective, and (2) the maximum allowable strut load (Cs) for
a 1-ft. long sample (Figure I below).
Allowable Uniform Load (U):
Values indicated in the rows adjacent to "U" are
of the (1) maximum allowable uniform loads considering channel flexure
and (2) maximum grating surface flexure.
Deflection Corresponding to "C":
Deflection values indicated below "C" values in the tables are the
mid-span, side channel deflections produced when the allowable concentrated
load is placed at mid-span.
Deflection Corresponding to "U":
Deflection values are indicated below the uniform
loads and are the mid-span side channel deflections for
the planks carrying the allowable uniform loads (Figure
III below).
Hot rolled Steel:
Steel that has been heated, flattened then coiled in a large
roll.
Pickled steel:
A process to chemically remove scale or oxide from steel to
obtain a clean surface.
RR-G-1602A:
Federal specification that mandates the anti-slip values for materials
used in certain situations.
Serrated:
A row of small sharp projections resembling the
teeth of a saw. |
