Questions

1. Q1

   1. a)

      A T-beam has the following details: flange width = 1000 mm, web width = 250 mm, flange thickness = 100 mm, effective depth = 500 mm, area of reinforcement = 2200 mm 2 . Use M20 concrete and Fe 500 steel. Determine moment of resistance assuming the flange in compression.

   2. b)

      Define the following terms used in Limit State Method: i) Characteristic strength ii) Characteristic load iii) Partial safety factors for materials iv) Partial safety factors for loads. Also explain why partial safety factors for loads are different for dead load, live load and wind/earthquake load.

3. Q3

   1. Design the slabs S-1, S-2, S-3 and S-4 shown in Fig. 1. Consider the width of the beam as 300 mm. The imposed load on the slabs S-1 to S-6 is 4 kN/m 2 and 2 kN/m 2 on S-7. Use M30 grade of concrete and Fe 500 grade steel. The design should include all assumptions, design steps, checks for deflection and strength and details of reinforcement in the slabs.
