Design a rectangular reinforced concrete beam for a simple span
of 35 ft. Uniform service loads are 1.0 kip/ft dead load (excluding
the self-weight of the beam) and 1.2 kips/ft live load. Use
f′c=4,000 psi and fy=60,000 psi. Sketch your design.
Design a rectangular reinforced concrete beam for a simple span
of 32 ft. Uniform service loads are 1.5 kips/ft dead load and 2.0
kips/ft live load. Assuming that the total depth h is not to exceed
32 in. and that there is no limitation on the width b. Use f′c =
3000 psi and fy = 60,000 psi. Sketch your design
(1) Select the lightest, rectangular Douglas fir section for the
cantilever beam of15- ft span that will carry a uniform load of 450
lb/ft. [Hint: V max = wL; Mmax = wL2/2]
A rectangular beam carrying a uniform load of 26 KN/m including
its own weight is limited in cross section to 300 mm x 500 mm. The
beam is simply supported in a span of 6 m. Using fc = 7 Mpa, fs =
124 Mpa, n = 12, ?? = 40 ???, ?? = 1.7 ???, ?????? ?ℎ? ????. Allow
65 mm distance from centroid of steel bars to extreme fibers.
1. A 3.5 m clear span singly reinforced cantilever
beam has a rectangular section of b=300mm and D=500
mm is reinforced with 2 bars of 32 mm diameter and 1 bar of 25mm
diameter in the tension zone. The
live load taken by the beam is 19 kN/m. Check if the beam is safe
to carry the above load . Use M25
and Fe500.

A 12 in. x 18 in. rectangular beam has an effective span of 20
ft. A dead load of 1500 lb/ft (includes self weight) and a live
load of 4000 lb/ft is applied to the beam. The concrete and steel
strengths are 4000 psi and 60000 psi respectively. Design and
detail the shear reinforcement for the beam. Assume d is 2 inches
less than h
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 beam extends over a span of 7.3 m and an overhang (cantilever)
to the right of the right support of 3 m (that is, the total length
of the beam is 10.3 m.) The beam supports a service dead load of 18
t/m that does not include self-weight, and a service live load of
10 t/m. Assume the connection between the beam and the support is a
simple pin or roller.
. If self-weight is 1.512 , the height(h)...
