2, Shear
Strength Parallel
to Rafter
Three samples
were tested for
shear strength
on June
29,201I
using a
United Universal
testing machine.
Samples
were rigidly
attached to the testing machine
and a shear load
was applied
to the 5/16"x1"
machine
bolt connected
to the
aluminum standoff. The samples
were loaded
parallel
to rafter
at
a
constant rate
of axial
deformation of 0.01 in./min. without
shock until failure
occurred. Based
on the
above
testing, the
average ultimate
shear
load, parallel
to rafter,
of the
QMLSH-7
hardware in Douglas
Fir
was determined
to be 803 lbf.
The
specific
gravity
and moisture content
of the
rafter
was tested in
accordance with
ASTM D2395,
Method
A
(oven'dry).
The average
specific
gravity
and moisture
content was
determined to be 0.438
and i3.8%, respectively.
Detailed
results are
provided
in Table
II. Typical
test setup is illustrated
in
Figure 2
of Appendix B.
3. Shear Strength Perpendicular
to Rafter
Three
samples were
tested for shear
strength on June 30, 2011 using
a United
Universal testing machine.
Samples
were rigidly
attached to the
testing machine and a shear load
was applied
to the 5/16"x1"
machine
bolt connected
to the aluminum
standoff. The samples
were loaded
perpendicular
to rafter at a
constant rate ofaxial
deformation
of 0.01 in./min. without shock
until failure
occurred. Based
on the
above testing,
the average
ultimate shear load,
perpendicular
to rafter,
of the
QMLSH-7
hardware in
Douglas
Fir was determined
to be
583
lbf.
The specific
gravity
and moisture
content
of the
rafter was
tested in
accordance
with ASTM D2395,
Method
A
(oven-dry).
The average
specific
gravity
and moisture
content was
determined to be 0.451
and
16.5%o, respectively.
Detailed results
are
provided
in Table
III. Typicat
test setup is illustrated
in
Figure 2 of Appendix
B.
