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 the AISC steel section name which has been checked against the steel code or has been selected.
-
RESULT prints whether the member has PASSed or FAILed. If the RESULT is FAIL, there will be an asterisk (*) mark in front of the member number.
-
CRITICAL COND refers to the section of the AISC code which governed 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 moment in local z-axis respectively. Although STAAD does consider all the member forces and moments 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.
- If the parameter TRACK is set to 1.0, the program will block out part of the table and will print the allowable bending stresses in compression (FCY & FCZ) and tension (FTY & FTZ), allowable axial stress in compression (FA), and allowable shear stress (FV), all in kips per square inch. In addition, member length, area, section moduli, governing KL/r ratio and CB are also printed.
- In the output for TRACK 2.0, the items Fey and Fez are as follows:
| Fey = 12π2E/[23⋅(KyLy/ry)2
| |
| Fez = 12π2E/[23⋅(KzLz/rz)2
