Study Notes

Cantilever Retaining Wall

  • The cantilever retaining wall has a height of 6 meters.
  • The active pressure on the wall varies from zero at the top to 35 kN/m at the bottom.
  • The modulus of elasticity (E) is constant throughout the wall.
  • The problem requires the computation of the maximum shear force in the wall.

Retaining Wall Characteristics

  • The retaining wall is a 6 m cantilever wall.
  • The active pressure on the wall varies along its height.
  • The active pressure is zero at the top of the wall.
  • The active pressure is 35 kN/m at the bottom of the wall.
  • The modulus of elasticity (E) is assumed to be constant.

Problem Objective

  • Compute the maximum shear in the 6 m cantilever retaining wall.
