The critical values of axial force, bending moment and shear force on a
reinforced concrete pile, having length 12 m and diameter 400 mm, at service
conditions are 400 kN, 20 kNm and 15 KN respectively. Design the pile and

sketch the reinforcement details.

Design a pile cap on a group of four friction piles each of 350 mm diameter
for supporting a 500 mm diameter column carrying an axial load of 1150 kN
at service condition. M25 grade concrete and Fe 415 grade steel are used for

the pile cap. Do necessary checks.

PART C
What is well foundation and its significance? What are the different types of
well foundation?

Sketch different types of retaining walls.

With suitable sketches explain the elements of well foundation.

Write down the design procedure of well cap and well steining.

Design a reinforced concrete cantilever retaining wall to retain 5m high earth
with horizontal surface at the top. The retained soil is well drained medium
dense sand of unit weight 18 kN/m? and angle of repose of 30°. The material
under the base is same as above with SBC of 150 kN/m’*. Coefficient of
friction between the base and the soil is 0.55. M20 grade concrete and Fe 415

grade steel are used for the retaining wall.
