The frame below has wind load and dead as shown. Use w(Dead) = 6
kip/ft and w(Live) = 3 kip/ft, L = 30 ft and H = 15 ft. The beams
and columns have modulus of elasticity E of 29000 ksi and moment of
inertias I(beam) = 2000 in4 and I(column) = 800
in4. Similarly they have cross-sectional areas A(beam) =
20 in2 and A(column) = 25 in2. Consider that
the wind can act in both horizontal directions.

. Design a beam for a 30-ft simple span to support the working uniform loads of wo 1.25 k/ft (includes beam self-weight) and wi-1.75 k/ft. The maximum permissible total load deflection under working loads is 1/360 of the span. Use 50 ksi steel and consider moment, shear and deflection. The beam is to be braced laterally at its ends and the mid-span only. (25-POINTS)
The truss shown is used to support the floor deck. The uniform load on the deck is 3k/ft. This load is transferred from the deck to the floor beams which rest on the top joints of the truss Determine the force in cach member of the truss, and state if the members are in tension or compression Assume all members are pin connected 16 I1 12 m 12 1 12 n
