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 (q) applied on the beam must add beam self-weight (concrete) to this value b) Uniform live load (qu) applied on the beam. c) Horizontal wind force (H H=12kip 12 x 20 gp-1.4 kip/ft -2.0 kip/ft 14 ft 12" x 12...
m 3: (20 points) Design the stirrup spacing for the beam shown below. Change your design between Zones 1, 2, and 3 of the beam length, using a uniform spacing in each zone. Ignore the self-weight of the beam. Loads on the beam are service loads so load factors must be applied according to ACI 318 (subscripts "d" and T" denote dead and live loads, respectively). Material strengths are fe 4,0oo psi and fy 60,000 psi. The total factored shear...
Problem 3 (5 points) A rectangular concrete beam of width b 24 in. is limited by architectural considerations to a maximum total depth h - 17 in. It must carry a design moment demand, M 400 kips-ft. Design the flexural reinforcement for this member. Use compression steel if needed. The concrete material has compressive strength of fe- 4 ksi. The steel conforms to ASTM A615 Gr. 60. Select reinforcement to provide the needed areas and show a sketch of your...
Problem 6 (15 pts) The beam shown is subjected to a vertical shear force of 70 kips and is fabricated by fastening the C12 × 20.7 and S20-96 rolled steel members with pairs of 0.75 in. diameter bolts as shown. The allowable shear stress of a bolt is 25 ksi. Determine the maximum spacing. C channel S section
