Question
![3. A 24 ft long, simply supported beam carries only a uniform live load (W). The beam has the
following properties:
f,= 60 ksi
f= 3,000 psi
• b = 14 in
d = 26 in
• h = 30 in
Steel: contains five (5) # 8 bars.
a)
Compute the depth of the compressive stress block (a) and the actual percentage of
reinforcement (p).
b)
Compute the R value and use this to compute the moment capacity (M.) in kip ft.
c)
Use the M; value to solve for the ultimate moment (M.). The use this value to solve for the
uniform live load (WL) in units of k/ft without the live load service factor (1.6).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fb85000d4-0ac2-42d7-8ae3-3f9b5b4d4879%2F1b260846-22ae-4d24-b57c-827f86947e54%2Fqn729in_processed.jpeg&w=3840&q=75)
