Question

A 356 x 171 US45 steel beam is simply supported at the ends of a span of 5.5 m. The beam carries a safe inclusive UDL of 12kN/m and a point load of 75 kN at mid-span. Calculate the maximum deflection due to this load.

Let:

E = 205 000 N/mm2

I = 12070 cm^{4}

deflection δ_{PL} = PL/48EI

deflection δ_{udL} = 5wL^{3}/384EI

Answer #1

. A simply supported beam has a width of 200mm and
depth of 400mm is 4m long. It carries a
uniformly distributed load of 20 kN/m over the whole beam and a
point load of 40 kN at the
center of the beam. Compute the maximum deflection if the maximum
slope produced in the
beam is 2× ??-3 radian.

depth of 400mm is 4m long. It carries a
uniformly distributed load of 20 kN/m over the whole beam and a
point load of 40 kN at the
center of the beam. Compute the maximum deflection if the maximum

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.

Blease i want prompt clear solution for this question in
detail,.

For a simply supported beam of length L and uniform
cross-section (constant E and I with usual notation) with a
concentrated load P perpendicular to the beam at mid span, use
first principles and method of integration discussed to obtain an
expression for the maximum deflection.
If the concentrated load is still perpendicular to the beam but
not at the mid span, very clearly and briefly explain how you would
determine the maximum deflection of the beam.

A simply supported beam is 3 m long. It carries a uniformly
distributed load of 6 kN/m throughout its span and a concentrated
load of 15 kN at a point 2 m from the left support. Assuming that
the beam has a rectangular shape whose width and depth are 150 mm
and 250 mm, respectively. Determine the maximum flexural stress in
MPa developed in the beam.

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.

A simply Supported Steel "I Beam" is made of three 1" x 7"
plates with a mass of 898.4 lbm each as shown below. Steel has a
modulus of elasticity of 30x10^6 psi. The beam is allowed to
deflect 1.10 in. The length of the beam L between supports is 10.5
feet.
a) If i turn the same beam clowise 90 degrees, what percentage
of the problem 20 maximum load can i apply to yield the same 1.10
inch deflection?...

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

A simply supported beam of 6m length carries a dead load of 10
kn/m and live load of 8 kn/m. It also support a point dead load of
60Kn at the centre. Using the formula calculate the moment
modification factor.
