There are 3 design criteria for the design of blocks. First is the bearing criteria, in which we make sure that the size of the block and service loads applied should be less than allowable bearing capacity. Second criteria is to ensure sliding due to horizontal thrust has a safety factor of...
Its no more simple vertical load rather there will be two components, one causing downward compression and the other causing bending in the wall. So, you have to calculate the eccentricity and compare the demand strength with the available strength. You can get the using Fs/fs+Fb/fb<1, where Fs...
The procedure is similar to that of the normal wall footing however, at every step you have to ensure that the one way shear at the step is within allowable limits. You can check that with the help of code formula.
