The CP 65 implementation in RAM Concrete Beam conforms to CP 65-1:1996 "Code of practice for structural use of concrete - Part 1: Design and construction". This code is hereafter referred to simply as CP 65.

Given that the CP 65 design code is virtually identical to BS 8110-1:1997, with the exceptions of the differences described in the following section, the implementation of CP 65 in RAM Concrete Beam is identical to that of BS 8110 and the technical details related to BS 8110 can be taken to apply to CP 65.
