Both the Intermediate and Special Moment Frame design as specified in ACI 318-99, Chapter 21 have been implemented. The concrete beam and column optimization and design check attempt to satisfy all the related code sections that have been implemented as outlined below. Due to the intricacies of the special provision section, in some cases the optimization may not produce an acceptable design and will identify one or more design warnings. In such cases there are a number of ways to eliminate the design warnings. These include changing the design criteria, changing member sections, or manually redefining the reinforcement.

The engineer will find a number of sections in Chapter 21 that have not been implemented. In most cases this is because these sections relate to detailing and are outside the scope of the program.
