The ACI 318-08 design code implementation in RAM Concrete Beam utilizes the majority of the design logic contained in the ACI 318-05 code, as is the case with the design code itself. This section documents changes made to the implementation from ACI-318-05 to ACI 318-08; specifically, additional checks required by the newer design code, modifications to existing sections, and design checks that are no longer necessary in the newer code.
