Two equations are developed.
Reinforced concrete stocky wall is where the effective height he divided by the thickness h does not exceed 15 for a braced wall and 10 for an unbraced wall.
Rcc wall is.
The example focuses on the design and detailing of one of the reinforced concrete walls.
There are 6 columns between it and the next shear wall.
In this example the structural design of the three retaining wall components is performed by hand.
Floor slabs frame into it at 3 2m centres and are 200mm thick.
