Transcribed Image Text:2. A 24 ft long, simply supported beam carries only a uniform live load (WL). The beam has the
following properties:
fy= 60 ksi
⚫
fo= 3,000 psi
•
b = 14 in
•
d = 26 in
•
h = 30 in
a)
• Steel: contains five (5) # 8 bars.
Use equation 13.3.3 from the text to compute the depth of the compressive stress block (a).
b)
Calculate the actual percentage of reinforcement (p). Do not use the value from Table 13.2
because this assumes the beam is balanced
c)
d)
Compute the R value and use this to compute the moment capacity (M+) in kip ft.
Use the M+ value to solve for the ultimate moment (Mu). 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).
