-------------------------------------------------------------------------------------------------------------------------------

Time Allowed: - 03 Hours. Marks: -75

Note: - Attempt any five questions. Each question carries equal marks.

Q.1: - Explain the difference between: -

  1. a) Elastic Theory method
  2. b) Load Factor method of designing the beam clearly.

Q.2: - A beam is required to transmit a bending moment of 17,00,000 Kg-cm.

Assuming the breadth of beam = 24 cm

Calculate the effective depth and required area of tension steel using (1000 – 20,000 – 15)

concrete.

 

Q.3: - A flight of stair consisting a 12cm risers and 25cm treads is required to span a horizontal

distance of 400 cm between supporting beams at the top & bottom of the flight. Design the

stair assuming a live load of 300 kg/cm2 and (50 – 1500 – 18) concrete.

Q.4: - Determine the dimension for a column carrying a load of 80, 000 Kg. Assume 2% steel

and fcc = 50 Kg/cm2, fsc = 1500 Kg/cm2.

 

Q.5: - Design a R.C.C footing for a column having 12″x12″ dimensions. The permissible bearing

pressure is 1.75 tons/ft2. Assume the missing data.

Q.6: - Design an edge supported R.C.C floor slab for a Residential house having size 20′x30′.

make an allowance for the ¾″ thick Terrazzo floor finish and 10ft high & 4 ½″ inch thick,

brick partition wall. Assume all the missing data or (1000 – 20,000 – 15) concrete. Sketch

the design also.

Q.7: - Write short notes on the following : - a) Tension and compression zones in beam

  1. b) Bending Equations for beam
  2. c) Over Reinforcement & under Reinforcement
