The Assign > Size command is used to assign a different section size to concrete beam members in the model. This command operates on an individual beam span basis and thus the sizes of individual beams, not entire beam lines, are changed by this command.

Note that once a member size is changed in the Concrete Beam module, the member analysis force results obtained from RAM Concrete or RAM Frame become approximate since the analysis results do not reflect the modified member size. In order to obtain exact member forces, the RAM Concrete analysis and, if applicable, RAM Frame analysis must be run again with the modified size.
