Question Paper
A section of a reinforced beam having width as 300 mm and depth as 550 mm is subjected to a service load moment of 175 kNm. Assume M 20 concrete and Fe 415 steel with O'cbc=7MPa and O'st=130 MPa. Determine the stresses in concrete and steel at the section. Determine the ultimate moment of resistance for a T-section having bf= 850 mm, Df =100 mm, bw =250 rom, d =520 mm and Ast =3695 mm^2. Assume M 25 concrete and Fe 415 steel. All notations have their usual
meaning.
2. Determine the ultimate moment of resistance of a doubly reinforced section with the following data:
b =300 mm, d =655 mm =45 mm,
Asc =982 mm^2,Ast 1964 mm^2.
Consider M 25 concrete and Fe 415 steel.
3. Design a one-way slab, with a clear span of 4·0 m which is simply supported on 230 mm thick masonry walls. It is subjected to a live load of 4 kN/m^2 and surface finish of 1 kN/m^2. Take Fe 415 steel and M 25 concrete. Assume that the slab is subjected to moderate exposure conditions.
4.(a) Design the reinforcement in a column of size 450 mm x 600 mm, subjected to an axial load of 2000 kN under service load conditions. The column has an unsupported length of 3·0 m and is braced against sideway in both directions. Use M 25 concrete and Fe 415 steel.
Discuss various stability conditions for a long column.
5. Design an isolated footing for a square column, 450 x 450 mm, reinforced with 8 -25 bars, and carrying a service load of 2300 kN. Assume soil with a safe bearing capacity of 300 kN/mm^2 at a depth of 1·5 m below ground. Assume M 20 grade concrete and Fe 415 grade steel for the footing.
6. Design the stem of a cantilever wall to retain earth with a backfill sloped at 20° to the horizontal at the top of the wall which is 5·5 m above the ground level. Its foundation depth may be taken as 1·2 m below the ground which has a safe bearing capacity of 120 kN/m^2. Assume that the backfill has a unit weight of 17 kN/m^2 and an angle of shearing resistance of 35°. Coefficient of friction between soil and concrete may be taken as 0.55. Use M 20 concrete and Fe 415 steel.
