Kicker of reinforced concrete cantilever retaining walls, Civil Engineering

Assignment Help:

Q. Kicker of reinforced concrete cantilever retaining walls located at the position of largest moment and shear force - why?

Generally for reinforced concrete cantilever retaining walls, there is a 75mm kicker at the junction wall stem and base slab to facilitate the fixing of formwork for concreting of wall stems. If a higher kicker (which is more than 75mm height) is provided instead, at the time of concreting of base slab the hydraulic pressure built up at kicker of fresh concrete cause great problem in forming a uniform and level base slab.  

Even though the fact that position of kicker in a cantilever retaining wall is the place of largest shear andflexure, there isn't any option left however to provide the kicker at this position.
