A truss is similar to the one shown in Fig. 7.A except the span is 36 ft, D 10 psf and S 20 psf. The top chord is a 2
 10 of No. 2 Hem-Fir, and it is laterally supported along its length by roof sheathing. There is no reduction of member area for fasteners.
= 1.0,
 = 1.0, and
 = 1.0. Joints are assumed to be pin-connected.

Find: a. Check combined compression and bending in the top chord using ASD.

b. Check combined compression and bending in the top chord using LRFD.
