D1.J.7 Tabulated Results of Steel Design

For code checking or member selection, the program produces the results in a tabulated fashion. The items in the output table are explained as follows:

Member: the member number for which the design is performed.
TABLE: AISC steel section name which has been checked against the steel code or has been selected.
RESULTS: prints whether the member has PASSed or FAILed. If the RESULT is FAIL, there will be an asterisk (*) mark on front of the member.
CRITICAL COND: the section of the AISC code which governs the design.
RATIO: prints the ratio of the actual stresses to allowable stresses for the critical condition. Normally a value of 1.0 or less will mean the member has passed.
LOADING: provides the load case number which governed the design.
FX, MY, and MZ: provide the axial force, moment in local Y-axis, and the moment in local Z-axis respectively. Although STAAD does consider all the member forces and moments (except torsion) to perform design, only FX, MY and MZ are printed since they are the ones which are of interest, in most cases.
LOCATION: specifies the actual distance from the start of the member to the section where design forces govern.

Note: If the parameter TRACK is set to 1.0, the program will block out part of the table and will print the allowable bending stressed in compression (FCY & FCZ) and tension (FTY & FTZ), allowable axial stress in compression (FA), and allowable shear stress (FV).
