RE: Design Properties for Western Red Cedar

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Western Red Cedar (dry)   E = 1110 ksi  w = 24.0 pcf @ 20% m.c. and 20 pcf @ 0% m.c.  (interpolate)
G varies dependent upon which plane.  Glr/E=.064      Glt/E=.061      Grt/e=.003 for Sitka spruce
 Glr/E=.075      Glt/E=.069      Grt/e=.011 for Yellow Poplar
Hope that helps

Currently I am designing a replacement 115kV T-line using Western Red
Cedar poles.  In so doing, I am also attempting to check the design
values used by PLS-CADD for Western Red Cedar.  I was wondering would
anyone know: Modulus of Elasticity, Modulus of Rigidity, and Density of
the aforementioned timber product.  Thanks in advance.
