Question

1. Calculate the maximum soil pressure.

2. Calculate the minimum soil pressure.

3. Design the spacing of the main reinforcement of the stem section of retaining wall using 28 mm diameter bar. Consider a load factor of 1.6, clear concrete cover of 75 mm and 12 mm diameter bar ties. Round off to whole number in mm.

A 6.0 m cantilever retaining wall with a surcharge of 15 KPa on the level of backfill.
Use the following values:
soil weight = 18 KN/m3,
concrete weight = 23.5 KN/m3,
angle of internal friction of soil = 33 degrees,
coefficient of sliding friction (concrete on soil) = 0.5,
compressive strength of concrete = 21 MPa;,
yield strength of steel = 414 MPa,
allowable soil pressure = 250 kPa.
