Hi,
The edge reinforcement shown in the output is per the edge. The format that is followed to calculate the reinforcement is "number of bars along thickness +2 X number of bars along the faces".
If there are two layer of reinforcement, then the reinforcement reported should be distributed half in each layer as it is a two layered reinforcement. The reinforcement distribution between layers should be 50-50.
For horizontal and vertical direction, the reinforcement is reported per layer.
