Concrete Cantilever Retaining Walls:
Rankine Formula
- Calculate active earth pressure coefficient,
earth pressure, horizontal resultant and moment.
Slip plane angle
- Calculate the slip plane angle of the soil for the soil pressure
wedge calculation, directly for noncohesive soils and by trial and error for
cohesive soils.
Wedge method
- Calculate soil pressure resultant with or
without a surface surcharge by the approximate wedge method.
Bearing pressure resultants
- Calculate the bearing pressure resultants for the toe and heel
of a concrete cantilever retaining wall to be used in the reinforcement
calculations.
Stem section reinforcement
- Calculate the distance to steel and the area of steel
reinforcement for the stem section of a concrete cantilever retaining wall.
Heel section reinforcement
- Calculate the distance to steel and the area of steel
reinforcement for the heel section of the base of a concrete cantilever
retaining wall.
Toe section reinforcement
- Calculate the distance to steel and the area of the steel
reinforcement for the toe section of the base of a concrete cantilever retaining
wall.
Stem steel development
length
- Calculate the development length for the steel reinforcement of
the stem section of a concrete cantilever retaining wall.
Design Problem 1
- Calculate the lateral earth force acting on a retaining wall using the wedge method.
Design Problem 2
- Calculate the lateral earth force acting on a retaining wall using the Rankine Formula.
Design Problem 4
- Check the resistance to sliding, the turnover stability, the bearing capacity and calculate the required areas of steel reinforcement for a proposed retaining wall.
