Steel beams may be designed per requirements of seven different codes including AISC 360-05 (ASD and LRFD), Allowable Stress Design (ASD), Load and Resistance Factor Design (LRFD), Canadian (CAN/CSA - S16.1 - 94), British (BS5950:1990 or 2000), Eurocode and AS 4100-98. C-Beam™ may only be design according to the ASD and LRFD codes. Joists are not designed by the program but rather selected from the manufacturer's table of Total and Live Load capacities. These tables are in the RAM\Tables directory, they have the extension .JST and may be edited with any text editor. For more information about design codes see the Design Codes Section in the RAM Steel Beam on-line documentation. For more information about joist tables see the Tables section in the Manager manual.

To establish the design code for steel beams:

• Select Criteria > Steel Design Codes.

• Click [OK].
