Questions

  1. Q1

    1. a)

      Explain balanced and under reinforced section with suitable sketch.

      [4]
    2. b)

      A beam of size 230mm × 550mm effective depth is simply supported over a span of 5m. The reinforcement consists of 5 bars of 20mm diam- eter at tension face. Find intensity of uniformly distributed load (including self-weight) that can be carried by beam. Use M25 & Fe415.

  2. Q2

    1. a)

      Explain the terms bond stress and development length. Calculate devel- opment length for 16mm diameter bar of grade Fe500 and M30 grade of concrete in tension and compression using LSM.

  4. Q4

    1. a)

      What is the purpose of partial safety factors used in LSM? Give the partial safety factors for stresses in steel and concrete.

      [2]
    2. b)

      A RC slab is to be provided for a passage measuring 8.5m×2.5m with 230mm wide beams around all edges. Design the suitable slab assuming LL 4kN/m 2 and FF 1.0kN/m 2 . Use M30 and Fe500. Assume moderate exposure condition. Show details of the reinforcement.
