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

refers to the member number for which the design is performed.

TABLE

refers to 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

refers to the section of the BS5950 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.

TRACK

If the parameter TRACK is set to 1.0, the program will block out part of the table and will print the allowable bending capacities in compression (MCY & MCZ) and reduced moment capacities (MRY & MRZ), allowable axial capacity in compression (PC) and tension (PT) and shear capacity (PV). TRACK 2.0 will produce the design results as shown in section 2B.9.

An example of each TRACK setting follows:
