A simply supported rectangular concrete beam is 18 in. wide and
has an effective depth of 32 in. The beam supports a factored load
(wu) of 15 kips/ft. on a clear span of 22 ft. The given load
includes the weight of the beam. Use f'c = 4,000 psi. and fy =
60,000 psi.

A simply supported reinforced concrete beam has a width (b) of
14 inches, and an effective depth (d) of 24 inches. It is
reinforced with 3 # 8 bars. Assume 60-ksi steel and 3000-psi
concrete. Determine the resisting moment (Mr) in ft-k that this
beam can safely sustain.
Problem 2
The beam given in Problem 1 has a span of 21 ft. It is supposed
to carry a uniformly distributed service dead load of 3.7 k/ft, in
addition to its...

A rectangular RC beam is simply supported over a span of 8m and
carries a dead load of 15kN/m (including self-weight) and an
imposed load of 8kN/m. The beam is 250mm wide and has an effective
depth of 400mm. Grade 30 concrete is to be used.
Determine if the beam should be singly reinforced or
doubly reinforced.

simply supported timber beam is 14 feet long with
cross-sectional dimensions of 4 in. wide by 10 in. tall. The beam
is supported at its ends and carries a concentrated load of 5 kips
at its center. The modulus of elasticity is 1.7×106
psi.
The deflection at the center is most nearly

Problem 1
A simply supported reinforced concrete beam has a width (b) of
14 inches, and an effective depth (d) of 24 inches. It is
reinforced with 3 # 8 bars. Assume 60-ksi steel and 3000-psi

Please select the reinforcement spacing for the entire span of a
simply supported beam on a 22 ft span. Use the detailed method to
calculate Vc. Do not use a shear envelope diagram use the regular
shear force diagram. Use b = 16 in., d = 27 in., the main bending
reinforcement consists of 4 #9 bars. The unfactored dead and live
loads are 2.6 Kip/ft and 2.5 kip/ft, respectively, f’c = 4500 psi,
and fy = 60,000 psi. Use...

A simply supported reinforced-concrete beam has to resist a
maximum factored moment of M* = 210 KN-m. Given that f’c = 32 MPa,
fy = 500 MPa and that the maximum possible width for the beam is
240 mm: a. Establish an appropriate structural depth ‘d’ for the
beam b. Determine the total depth ‘D’ of the beam for a FRL of 90
minutes c. Find the area of steel Ast required to resist the moment
and select the rebars....

Design a simply supported one-way reinforced concrete floor slab
to span 12 ft and carry a service live load of 180 psf and a
service dead load of 20 psf. Use fc’=3000 psi and fy=60,000 psi.
Make the slab thickness to 1⁄2 inch increments. (Hint: Design the
slab according to the ACI Code minimum thickness)

Calculate the total area of steel required in tension zone for a
simply supported beam of 230 mm wide, 406 mm effective depth. The
total ultimate factored moment on the beam is 146.76 kN.m. Assume
an effective cover for the compression reinforcement as 20 mm.
Mu,lim of the section is 130.76 kN.m. Use M25 grade concrete and
Fe415 steel. Check for spacing, shear and deflection is not
required.

A simply supported rectangular beam of 5m span carries a
characteristic dead, gk (inclusive of the beam’s self-weight) and
imposed, qk, loads of 15 and 7 kN/m respectively.
Given the following data:
Beam: 285mm wide and 500mm high, Reinforcement steel: High
tensile steel, Concrete grade: C30, Exposure condition: Mild and
Fire resistance = 1.5h.
Design the rectangular beam according to BS8110.
