Design Problem
Retaining Wall:
It is required to retain the 5.5 m high back fill by providing the retaining wall, The
properties of backfill material are , density of soil = 17.6 kN/m3, angle of internal
friction ϕ = 31 , allowable Bearing capacity = 180 kPa, The retaining wall to be
constructed is of concrete with density as 24 kN/m3, whereas fc’= 20Mpa, fy =
420Mpa, coefficient of friction between concrete and soil = 0.45.
You are required to decide dimensions of RW components, apply all stability checks
and design the reinforcement of the wall for strength.
Plot also the reinforcement detailing of the wall.
