A simply-supported beam has a 1 kip/ft uniformly-distributed load over the left half of its 9-ft span. What is the magnitude of the shear force at midspan?

Determine the lightweight modification factor, λ, for a rectangular beam with b = 16 in. and d = 21 in., three epoxy-coated No. 7 Grade 60 tension-reinforcement bars placed in the bottom of the beam, and No. 4 Grade 40 stirrups located every 12 in. along the span. Assume 5,000-psi lightweight concrete and a clear cover of 1.5 in.

Determine the bar-spacing factor, cb, for a simply supported rectangular beam with b = 18 in. and No. 3 stirrups. This beam has four No. 7 bars as longitudinal reinforcement. The clear cover is 1.8 in.
