RAM Structural System Help

Seismic Provisions

Both Intermediate and Special moment frame design as specified in ACI 318, Chapter 21 are implemented within RAM Concrete Beam. This section discusses the changes to the design process in RAM Concrete Beam when the Intermediate or Special Frame option is selected from the Frame Type Criteria dialog.

The concrete beam and column optimization and design check attempt to satisfy all the related code sections that have been implemented as outlined in this section. Due to the intricacies of the special provision section, in some cases the optimization may not come up with 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 design criteria, changing member sections or manually redefining the reinforcement.

The engineer will find a number of sections in ACI Chapter 21 that have not been implemented. In most cases this is because the sections relate to detailing and are outside the scope of the program. There are also sections that may be picked up by the engineer in construction notes on the structural documents.
