Hi

Abr depends on the settings you specify on two dialog boxes:

1- Calculation options

2- Reinforcement patterns

For small moments the theoretical area of reinforcement needed to handle it may be small but the code has got some provisions for (larger) minimal reinforcement (Abmin). For such reinforcement Mc may be higher than the actual value of M.
