Equations
The equation for
rho
is given by:
rho=1+G(0.9)MCG(1+MC)
G
is the specific gravity of a wood species (unitless)
👉See Table 4A of NDS Supplement notes for values of G based on your wood species
MC
is the in-service moisture content of the CLT panel, commonly taken as
12%
for mass timber members (unitless). Note, remember to input the MC as a decimal in the above equation, e.g.
