Question

Design for flexure a simple span beam 26’ long to carry PD = 1000# and PL = 2000# at the center of the span. f’c = 4,000psi and fy = 60,000psi. show all work, not in milimeters

Answer #1

Design for flexure: a simple span beam 26’ long to carry PD =
1000# and PL = 2000# at the center of the span.
f’c = 4,000psi
fy = 60,000psi
(show all work)

design a 12" wide beam with a simple span of 28′ to carry
PD = 2000lb & PL = 2000lb at the center
of the span f’c = 4,000lb/in2 fy =
60,000lb/in2
factor loads
estimate height
depth=h-2.75"
Estimate reinforcement – As =
Mu/4dest
Check minimum reinforcing
requirements
Asmin = (200/fy)bh
Asmin = 3(√f’c/fy)bh
Select Reinforcing Bars

design a 12" wide beam
with a simple span of 28′ to carry PD = 2000lb &
PL = 2000lb at the center of the span
factor loads 1.2D+1.6L
Calculate Mu = PuL/4
f’c = 4,000lb/in2 fy =
60,000lb/in2
estimate height
depth = h - 2.75
Estimate reinforcement – As =
Mu/4dest
Check minimum reinforcing requirements
Asmin = (200/fy)bh
Asmin = 3(√f’c/fy)bh
Select reinforcing

Design a simple-span one-way slab to carry a uniformly
distributed live load of 450 psf. this is the only load to be
supported other than the self weight of the slab. the span is 7-ft,
center-to-center of the supports. Assume f'c = 4000 psi, fy = 60000
psi. Design per foot of width.

design a simply supported floor beam of A992 steel to carry a
De0ad load of 0.5k/ft and a Live load of 1.5k/ft over a span 24 ft.
The beam has Full lateral bracing provided. Show All steps.
