1. Set B
1. A concrete Beam with a width of 350mm, total depth of 600 mm and an effective depth of 530
mm is reinforced with a steel with an Area 𝐴 = 2580 𝑚𝑚 the Beam must carry a Service
Moment of 130 kN.m. Calculate the Flexural Stress in the concrete using transformed-area
method if the modular ratio is equivalent to 9.
3. A simply Supported Beam with a span of 8 meters is to carry the following gravity loads. Dead
Load 25.72 kN/m, Live Load of 12 kN located at Midspan of the Beam. If the designer uses a
Section size of 250 mm width and 450 mm depth with a Concrete Cover of 40 mm. Consider
the Load Combination of 1.2DL+1.6LL. Use 𝑓′ = 28𝑀𝑃𝑎. 𝑓 = 415 𝑀𝑃𝑎. Use ∅ = 0.65 for
compression control, Use ∅ = 0.90 for tension control and calculate ∅ for transition Section ;
Use limiting amount of strain as 0.002 for compression and 0.005 for tension.
Calculate the number of 25mm RSB needed for the Beam
Calculate the Beam Reduction Factor
Calculate the Ultimate moment Capacity of the Beam
