Dr. A.P.J. Abdul Kalam University

Bachelor of Engineering

Sixth Semester Examination, June-2021

Structural Design-I (RCC) [CE-604]


Time: 3:00 Hrs Max Marks 70

Note: (i) Attempt any five questions out of eight.

(ii) All questions carry equal marks.

(iii) Assume suitable data if necessary & state them clearly.

Q.1 (a) Differentiate between Working stress method of design and Limit state

method of design?

(b) Define Neutral axis, Lever arm, and Effective depth and Section modulus?

Q.2 (a) What do you understand by Strength criterion and Serviceability criterion

clearly explain?

(b) Find the moment of resistance of a R.C. Beam 180×400mm. The beam is

reinforced with 4 to 12 mm diameter bars in tension zone. The effective cover to

the reinforcement is 30mm. Use M20 grade of concrete and Fe415 for steel.

Also state type of beam?

Q.3 (a) Elaborate various properties of concrete and reinforcing steel?

(b)For a Rectangular beam of size 250mm wide and 520mm effective depth find

out the depth of neutral axis, Balanced lever arm, Balanced moment of

resistance and balanced steel area. Also apply shear and development length

checks. The materials are M20 grade and HYSD steel of Fe-415.

Q.4 (a) Design a singly reinforced rectangular beam carry a live load of 55Kn/m.

Beam has a span of 5m. Use M20 grade of concrete and Fe415 steel HYSD.

Apply all strength and Serviceability checks.

(b) In case of singly reinforced beam at which position reinforcement will

provide and why it is provided?

Q.5 (a) A singly reinforced RC beam has an Effective depth of 400mm and a breadth

of 250mm. It contains 4-16mm bars. For M20 grade concrete and Fe415 grade

steel. Calculate the shear reinforcement needed for a factored shear force of



(b) Design a Simply supported roof slab for a room 8.0×3.5 meter clear in size if

the live load 4 KN/m2 . The slab is simply supported on all the four edges.

Exposure condition is moderate. Check for deflection also

Q.6 Design a Two way slab for a room size of 4.5×3.5m with end conditions are

simply supported and corners held down (Not free to lift up). Live load may be

assumed 6 KN/m2 and Floor finishing load 1.1Kn/m2

. Use M20 Grade concrete

and Fe415 steel. Also apply necessary checks

(b) Define under reinforced section and over reinforced section?

Q.7 (a) What are basic difference s between one way slab and two way slab?

 (b) Why Torsional steel is provided in case of two way slab?

Q.8 (a) Design a simply supported circular slab of diameter 5m. The slab is

subjected to uniformly distributed load of 4 KN/m2

(b) Design a short column subjected to carry an axial load of 1400KN. Factored

moment of resistance in one direction as 65KN-M and moment in other

direction as 45 KN-M
