SECTION-B
2. What are the various thumb rules for proportioning of a staircase?
3. Design a circular water tank with flexible bases for a capacity of 400 kl. The depth of
water is 4.5 m. Allow suitable free board.
4. Calculate the maximum bending moment for a semicircular beam supported on 3 equally
spaced columns, the centre of columns are on a curve of 10m diameter. The
superimposed load is 1500 Kg/m
2
.
5. Design a conical dome for hall 10m in diameter Rise of dome is 4m. Live load on the
dome may be taken as 2KN/m
2
. Use M20 concrete and Fe250steel.
6. Differentiate between the cantilever and counterfort retaining wall. Why counterforts are
provided?
SECTION-C
7. Design a rectangular footing of uniform thickness for an axially loaded column of size
300mm ? 600mm. Load on the column is 1100KN. Safe bearing capacity of the soil is
200 KN/m
2
. Use M25 concrete and Fe415 steel.
8. Design the stem and heel of a cantilever retaining wall to retain horizontal earthen
embankment of height 4m above the ground level. The earthen backfill is having density
of 18 KN/m
3
and angle of internal friction as 30?. The safe bearing capacity of the soil is
180 KN/m
3
. The coefficient of friction between soil and concrete is assumed to be 0.45.
Use M25 concrete and Fe415 steel.
9. Design a column of size 450mm ? 600mm having 3m unsupported length. The column is
subjected to a load of 2000 KN and is effectively held in position but not restrained
against rotation. Use M20 concrete and Fe415 steel.
NOTE : Disclosure of Identity by writing Mobile No. or Making of passing request on any
page of Answer Sheet will lead to UMC against the Student.
