Answer all questions
All questions carry equal marks

*****
1 Design an interior panel of a flat slab with panel size 6 x 6 m supported by columns 5 m x 5 m.
Provide suitable drop. Take live load as 4 kN/m
2
. Use M20 steel and Fe 415 steel. Draw plan and
sectional elevation.
OR
2 Design a circular cylindrical bunker of capacity 250 kN to store coal using M20 steel and Fe450 steel
and unit weight of coal is 8.0 kN/m
3
, angle of repose of coal is 25?C. Draw plan and sectional
elevation.

3 Design a cylindrical water tank of capacity 100cum resting on ground having a flexible base. The
material used in construction is M25 grade concrete mix and HYSD, Fe415 steel. The overall height
of the tank is restricted to 3.00 m with free board of 200 mm. The bearing capacity of soil at the site
is 150 kN/m
2
. Draw plan and sectional elevation.
OR
4 Design a cantilever retaining wall, which is required to support a bank of earth 4.0 m high above the
ground level on the toe side of the wall. Consider the backfill surface to be inclined at an angle of 15
with the horizontal. Assume good soil for foundation at a depth of 1.25 m below the ground level with
a safe bearing capacity of 160 kN/m
2
. Further assume the backfill to comprise granular soil with a
unit weight of 16 kN/m
3
and an angle of shearing resistance of 30 . Assume the coefficient of friction
between soil and concrete to be 0.5. Draw plan and sectional elevation.
