STAAD FOUNDATION - AREA REQUIRED 'FAILED' Message

Hi,

Please see attached file. Why is the program giving a message "area required - Failed"? What exactly does this mean? Please advise.

Thanks,

  • We suspect that for some of the load cases, the overturning moments on the mat are large and there isn't enough restoring moment to prevent the slab from overturning because the selfweight of the mat and soil weight above it are not included in the loads to be considered for any given load case. The yellow colored warnings that appear in the lower half of the screen are indicating that. It is responsible for the instability warnings that appear during the STAAD analysis.

    From the left side of the screen, go to Loads & factors - Apply Self Weight and Dead Weight factor, and set the value of the Dead Weight Factor to 1.0 for all the load cases. Then run the analysis again and see if it helps.
