Question

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.

Answer #1

A 5.3m long simply supported beam is subjected to a dead load of
23 and live load of 28 kN/m. If the beam has width, height and
concrete cover of 25cm, 50cm and 3cm respectively, design this
beam. Use C25 and S220. (if required; k1=0.85 and d’’=2cm)

A simply supported beam spans 30 ft. and carries a uniformly
distributed dead load of 3.5 kip/ft,excluding the beam self-weight.
Also, in addition, a concentrated dead load of 15 kips and a
concentrated live load of 25kips, both act at the center of a 30 ft
span.Select the lightest-weight W-Shape to carry the load(A992
steel). Use LRFD method.

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.

Calculate the bending capacity of a simply supported concrete
beam.
Beam is 6m long and supporting dead load of 20KN/m and live load
of 10KN/m. Compressive strength of the concrete is 25MPa and yield
strength of rebars is 500MPa.
Concrete beam is 300mm height 200mm width.

A simply supported beam spans 20 ft and carries a uniformly
distributed dead load of 0.8 kips/ft including the beam self-weight
and a live load of 2.3 kips/ft. Determine the required plastic
section modulus and select the lightest weight Wshape to carry the
moment. Consider only the limit state of yielding (Zone 1) and use
A992 steel. Design by (a) LRFD and (b) ASD.

overhanging beam is simply supported at san of 13m and carries of
point load of 4000N 3m from right support the left overhangs is 3 m
away from left support and has a point load of 5000N. the right
overhang is of 4m carrying UDL of 200N per meter for entire
rightover . draw shear force and bending moment diagram . calculate
the maximum bending moment.

Plot the shear force and bending moment digrams for an
8m long beam simply supported at 0m and 6m. There is a distributed
load of 10 KN/m between the two supports and there is a point load
of 20kN located at the end of 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.

Design the shown beam; if it is given that
Dead load, wd = 15 kN/m
Live load, wL = 10 kN/m
Beam breadth b = 300 mm
Beam height, h = ℓ/21 mm
where; Span, ℓ = 9; and S
is the student serial number according to the following table. Use;
fc = 35 Mpa and fy = 420
Mpa.

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.
