Problem 10 (If time permits?) The cantilever truss shown is loaded with two concentrated loads at joints C and E. Determine the vertical deflection of joint G using the method of virtual work. 140k to B A (4 in) C (3 in ²) (4 in²) 16' (4in¹) E (3 in ²) D (4in³) y 20k G 12'

1) Consider the elevation view of an interior beam shown below. The beam has a t-shaped cross- section (the 5 in. thick slab is cast monolithically with the beam - meaning that the 22 in. deep beam has 17 in. hanging below the slab). The c-c length is 30 ft. Assume: M bw = 14 in. fc = 6 ksi Mu,neg. = 340 k.ft en = 28.5 ft Wu h = 22 in. fy = 60 ksi Mu,pos = 230 k.ft Sw = 12 ft - Length hstab = 5 in. No. 4 stirrups Column FL a. Select flexural reinforcement for the beam at midspan assuming it is singly reinforced. T- beams under positive bending are usually singly reinforced because the depth of the neutral axis in the flange is often smaller than the depth of any bars that might be present. Iterate until the design strength, Mn, exceeds M₁ by less than approximately 20%. Provide a drawing of the section design that clearly shows the location of the longitudinal reinforcement. Show the section complies with relevant ACI Building Code requirements (As,min, bar spacing limits, Et, min). b.…
