1. A 24 foot steel beam of A36 steel is simply supported on its left end and 7 feet from its right end. A load of 3200 lbf/ft is uniformly distributed over its entire length. Lateral support at reactions only. The beams dead weight is 60 lbf/ft. Choose a W shape. Do not check shear.
2. Select an A36 W shape with lateral support every 6 ft to span 22 ft And carry a uniform load of 1.2 kips/ft Including a 50 lbf/ft dead load. Max deflection is L/240
3. A 60 ft steel beam carries a dead load of 1.5 kip/ft, excluding self weight, over entire span. Supports are at 0 ft (A), 30 ft (C), 55 ft(D) and a hinge is at 25 ft(B).
a) Find the reaction at 0 ft (A)
b) Find the Reaction at 30 ft (C)
c) Find the reaction at 55 ft (D)
d) Find the absolute minimum Shear value
e) Find the location of the maximum shear
f) Find the maximum Moment
g) Find the location of the maximum moment
h) Use unbraced length of 30 ft, find the best W18 section of A36 for moment capacity
i) Find the actual shear stress for the beam chosen
j) Using 42 ksi steel, for the same shape chosen, find the unbraced length that permits the development of 0.66Fy bending stress
