How can I get detail "design calculation output for a steel member "conforming to AS4100 code using staadpro SS6
You can use TRACK 2 command for getting a detailed output.
For a TRACK 2 output, the program will report all the relevant clause checks that have been performed and will also indicate the critical ratio and the load case that caused the critical ratio as well as the corresponding forces that were used for the respective checks.
TRACK 2
A TRACK 2 output will also include the various design data used for the calculations such as the section modulii, section class, section capacity etc.
