Structural Analysis of a concrete block

Need to perform structural analysis for precast concrete modular blocks. The blocks are used to make a retaining wall.
I will provide the block dimensions, and you need to determine how much reinforcement is needed.
Loading is very simple, just the self-weight and soil surcharge, and Live Load on top

Calculations have to be prepared in MathCAD to meet both AASHTO LRFD Code & ACI CODE (2 sets)
Analysis can be performed in either MathCAD or STAAD (you tell the best approach)

You have to be familiar with both AASHTO LRFD & ACI CODES
MathCAD for calculations
STAAD (if selected as a tool to determine stresses, moments, etc.)
I will contact the qualified person for the above skills
