Question

3. (40 pts) Analyze the following statically determinate frame by hand and clearly draw the shear force, axial force, and bending moment diagrams indicating relevant (maximum and minimum) values for each of the following load cases: a) Uniform dead load (qo) applied on the beam – must add beam self-weight (concrete) to this value. b) Uniform live load (q) applied on the beam. c) Horizontal wind force (H). H= 12 kip 11IIIIIIIIIIIIIIIIIIIII 12" x 20" 9.- 1.4 kip/ft 92= 20 kip/ft 14 ft 12" x 12" 12" x 12" 25 ft 25 ft (a) (b) 4. (10 pts) Using the results from Problem 3, obtain the ultimate (design) moment to be used for the left end of the beam and the center of the beam using ACI 318-14 load combinations. For this problem, the combinations that apply are given below for reference (the equation numbers correspond to those found in ACI 318-14). Indicate what face of the beam is in tension for each combination at each of the two sections indicated. U=1.4D (5.3.la) U=1.2 D + 1.6L (5.3.1b) U=1.2D+ 0.5 L + 1.0 W (5.3.1d) 19 = JE E RE E E : PFCFK ?
