Working with C-Beam

The commands in the Layout – C-Beam menu work essentially the same as their Layout - Beam counterparts. Refer to the Working with Beams section for a description of each command. The Layout –C-Beam commands are available in the Layout menu only when modeling in C-Beam™ material mode. When C-Beam members are added, the Composite Flag (i.e., Composite or Noncomposite) and Fy need to be specified. The Type of C-Beam, Castellated or Cellular, also needs to be specified.

Icon	Description
	One command unique to C-Beam is the Layout – Assign Duct Size command. This command is used to specify a duct size for which the beam openings are to be large enough to allow to pass through.
	The Options – Set Show Options can be used to highlight beams that have been assigned to be Castellated versus those assigned to be Cellular. Select the Castellated C-Beam or the Cellular C-Beam option on the Beam tab.

It is not necessary to assign sizes to C-Beam members; the optimum size and hole configuration will be selected automatically by the program in the RAM Steel Beam module. However, sizes can be assigned by the user if desired, using the Layout - Beam - Assign Beam Size command. The user may assign sizes for either Castellated or Cellular beams from either of two C-Beam Design Tables, the Default or Alternate, as specified in the Smartbeam tab in the Criteria - Design Steel Tables command in the RAM Manager.
