Bending and axial tension
posted in Timber Engineering |
Email This Post
Members subjected to combined bending and axial tension should be proportioned to satisfy the interaction equations
[ft/Fc'+ f b/Fb*]<=1
and
[(fb-ft)/Fb**]<=1
where
ft =tensile stress due to axial tension acting alone
fb =bending stress due to bending moment alone
Ft‘=design value for tension multiplied by applica- ble adjustment factors
Fb*=design value for bending multiplied by appli- cable adjustment factors except CL
Fb**=design value for bending multiplied by applica- ble adjustment factors except Cv
