Flexure: |
|
The following is for calculating the adjusted moment capacity of a wood member. |
|
|
|
|
|
Reference design value for bending (Fb - psi or kPa) |
|
|
*Section modulus of member (S - in^3 or mm^3) |
|
|
Load duration factor (Cd - for ASD only) |
|
|
Wet service factor (Cm) |
|
|
Temperature factor (Ct) |
|
|
Incising factor (Ci) |
|
|
Beam stability factor (CL) |
|
|
Size factor (Cf) |
|
|
Flat use factor (Cfu) |
|
|
Repetitive member factor (Cr) |
|
|
Time effect factor (TEF - for LRFD only) |
|
*For a rectangular bending member with neutral access
perpendicular to depth at the center, Section modulus, S = (bd^2)/6; b = width,
d = depth
