Code Check Criteria

The Frame Code Check Criteria report lists the criteria used in the Steel Standard Post-Processors. The sidesway condition, braced or unbraced, is indicated. The Effective Length (K-Factor) values for columns, beams and braces are listed. For columns, "Nomograph" (ASD/LRFD), "Appendix E" (BS5950) may be printed. This indicates that the effective length factor for ASD and LRFD will be calculated based on the nomograph published in the AISC Manual of Steel Construction, Appendix E in the BS5950.

The criteria used to determine the compression flange bracing conditions for columns and beams is listed

The Roof Live Load is indicated as being either Reducible or Snow. If Snow, the criteria and/or the load factor for including Snow loads in combinations with Seismic loads is indicated.

The criteria for Sidesway, Effective length and Compression flange bracing are specified from the Criteria menu command, or are assigned to individual members from the Assign menu command. The designation of Roof Live Load type is specified in Criteria - Live Load Reduction in RAM Manager. The criterion for Snow Factor is set in the Combinations-Generate menu command.
