Questions

  1. Q1

    1. a)

      A stair hall of a building measures 3.0 m × 5.5 m. The floor to floor height is 3.4 m. Design a dog-legged stair case resting on beams of size 230 mm. The design load on the stairs may be considered as 4 kN/m 2 . Adopt M-25 grade of concrete and Fe-500 grade of steel. Sketch the details of reinforcement.

    2. b)

      What are flanged sections? Explain how the flanged width is calculated.

  2. Q2

    1. a)

      Figure 1 shows the floor plan of a building. The beams are of size 230 mm × 450 mm. Beam B 1 is reinforced with 4-16# bars in tension and 2-10# in compression. The load on the slab is 6 kN/m 2 . Design the beam for shear. Adopt M-25 grade of concrete and Fe-500 grade of steel. Sketch the details of reinforcement.

    2. b)

      Explain the assumptions made in the IS code method of analysis of continuous beams.

      [3]

  4. Q4

    1. Design the beam A-B-C shown in Fig. 2. The load on the beam may be considered as 12 kN/m. Design the beam using M-20 grade concrete and Fe-500 grade of steel. Sketch the details of reinforcement.

  5. Q5

    1. a)

      How are reinforced concrete columns classified? Explain the modes of failure.

      [3]
    2. b)

      For the floor plan shown in Fig. 1, design column C 1 . Show how the column is oriented, The column is subjected to working load of 700 kN, working moment of 90 kN-m about major axis bisecting the depth of column. The unsupported length of column is 4.0m. The column is fixed at both the ends. Show detailed design calculations and reinforcement details. Use M-30 grade concrete and Fe-500 grade of steel.
