Sample CE8501 Question Bank DESIGN OF REINFORCED CEMENT CONCRETE ELEMENTS

1.Design a rectangular reinforced concrete beam simply supported on masonry walls 300mm thick with an effective span of 5m to support a service load of 8KN/m and a dead load of 4KN/m without its own weight. Adopt M20 grade concrete and Fe 415 HYSD bars width of support of beam=300mm.

A simply supported over an effective span of 8m carries a live load of 15KN/m. design the beam, using M20 concrete and Fe415 grade steel. Keep the width equal to half the effective depth. Use working stress method of design.

A singly reinforced beam 250mmX500mm in section in reinforced with four bars of 16mm diameter with an effective cover of 50mm. effective span of the beam is 6m.assuming M20 grade of concrete and Fe415 grade of steel determine the central concentrated load that can be carried by the beam in addition to its self-weight.

i).Discuss the terms of (a) Neutral axis (b) Moment of resistance (c) Lever Arm ii).A doubly reinforced beam with b =500 mm has to carry a dead load moment of 80,000 Nm and a live load moment of 100,000 Nm. Using M20 concrete and Fe415 grade steel, calculate the required steel using working stress method of design.

Design a rectangular section for a simply supported RC beam of effective span of 4m carrying a concentrated load of 35kN at its mid span. The concrete to be used is of grade M20 and the reinforcement consists of Fe415 steel bars. i) Self weight of beam is ignored. ii) Self weight of beam is considered. Choose working stress method.

6. A reinforced concrete beam of span 5m has a rectangular section of 250 mm x 500 mm. the beam is reinforced with 3 bars of 16 mm diameter on the tension side at an effective depth of 450 mm and 2 bars of 16 mm diameter on the compression side at a cover of 50 mm from the compression face. Estimate the maximum permissible
