Problem $3$:

A DF axial combination glulam is used as the tension member in a large roof truss.

Two rows of diameter bolts occur at the net section of the member. Loads are a

combination of dead and wind $($ASD: ; LRFD: $).$ Joints are assumed

to be pin$-$connected. Temperature $.$ Find: The maximum axial tension load using

ASD and LRFD for different moisture contents $($MC$)$:

a$)$ MC$=15\%$; b$)$ MC$=18\%$
