Problem Description
Foundations with top and bottom reinforcement and governed by the minimum reinforcement provision are under designed. Foundations with bottom reinforcement only are designed correctly.
Reason
In foundations with both top and bottom reinforcement, the program added the top and bottom reinforcement and applied the total area of steel to meet the minimum flexural reinforcement requirements in ACI 318 10.5.4, which refers to 7.12. The minimum flexural reinforcement requirement in 10.5.4 should be applied separately to the top and bottom reinforcement. This is clarified in ACI 318-14.
Solution
This issue corrected in version 15.05.00/41 and after.
