Hello,
I need help in solving these two questions for my structure design class. Please find the full questions on the attachment bellow. The answers could be through word document, or PDF.
INSTRUCTIONS: All the steps must be clearly shown. Whenever a value or any other information comes from book or code, table number and/or page number should be clearly mentioned. If any value that you need for calculations is not given, assume and state the basis of your assumption (based on book, reasoning etc.).
(If your PID is “5684659”, then A = 5, B = 6, C = 8, D = 4, E = 6, F = 5 and G = 9. Interpret 4.G as 4.9 in this example)
My PID is”5922531″, then A=5, B = 9, C = 2, D = 2, E = 5, F = 3 and G = 1.
1. (5 points) Determine M n for a beam of cross section shown in figure 1, where f’ c = 4 ksi.
Assume f y = 60 ksi. Calculate the strain on steel when the concrete strain is 0.003 and compare it with yield strain of steel.
Es = 29×10 3 ksi
2. (5 points) Determine if the beam shown in the figure is adequate as governed by the ACI Code (318-11). The loads shown are service loads. The uniformly distributed load is DL =
0.65 + 0.F = _________ kip/ft, LL = 0.55 + 0.E = ________ kip/ft. The dead load excludes the beam weight. The point load is a live load. f’c = 3,000 psi, fy = 40,000 psi.
In case you find that the section is not tension-controlled, use the closest value of . ONLY FOR THE SAKE OF SIMPLIFYING THIS PROBLEM, SHOULD NOT BE FOLLOWED ELSEWHERE.
