1. The wall elevation in the following figure is subjected to a maximum lateral force (strength level wind) of 3000 lbs. Use ASD.

a. Use the segmented shear wall approach to select an adequate sheathing and fastener spacing (comment on fastener spacing at panel edges and intermediate framing members).

b. Calculate the maximum uplift force that must be resisted by the tie-down anchors

c. Calculate the maximum forces in the tension and compression chords

3. The wall elevation in the following figure is subjected to a maximum lateral force (strength-level seismic) of 4000 lbs. Studs are spaced 14? on center (max). Use ASD.

a. Use the segmented shear wall approach to select an adequate wood-based panel sheathing and fastener spacing (comment on fastener spacing at panel edges and intermediate framing members). Be sure to include the wall seismic force assuming D = 20 PSF.

b. Calculate the wall deflection using NDS Eq. 4.3-1. Remember that strength-level forces must be used to calculate wall deflection. Chords are made up of back-to-back Hem-Fir No. 2 2x6s. ?a = 0.033 in. from manufacturer?s catalog.
