Question 14
Open questionCEMCQ1 markNeeds review
A rectangular singly reinforced concrete beam has a width of 300 mm and an effective depth of 550 mm. The grades of steel and concrete are Fe500 and M25, respectively. The area of steel in tension is 1963 mm
. The depth of neutral axis is 302 mm. The ratio of the limiting depth of the neutral axis (
) to the effective depth (d) of the beam is 0.456.The most probable mode of failure of the beam is

The required centre-to-centre spacing of 10 mm diameter bars is 150 mm to resist the design moment in a concrete beam. Instead of 10 mm diameter bars, if 12 mm diameter bars of the same grade are used, the required centre-to-centre spacing (in mm) to resist the same design moment becomes ______ (rounded off to the nearest integer).

Open questionCENAT2 marksNeeds review
A 250 mm wide × 600 mm deep rectangular concrete beam is prestressed by means of 4 high-tensile tendons, each of 14 mm diameter. The centre of the tendons is 200 mm from the soffit of the beam. The effective stress in each tendon is 700 N/mm².
The maximum bending moment (in kN-m), that can be applied to the section without causing tension at the soffit of the beam due to prestressing only, is ______ (rounded off to one decimal place).
Use π = 3.14

Open questionCENAT2 marksNeeds review
A simply-supported rectangular reinforced concrete beam has a width 250 mm and an overall depth 600 mm. The effective span of the beam is 6.23 m. The beam carries a live load of 5 kN/m and a super imposed dead load of 5 kN/m, in addition to its own weight. The unit weight of reinforced concrete is 25 kN/m³. Consider the load factor of 1.5 for all stated loads.
The design bending moment (in kN-m) for the limit state of collapse is ______ (rounded off to two decimal places).
