Ram concept 1

[wzBZ]

HI
I ran into a problem with their calculating in RAM concept which displays the message in the photo below; something that gives inconsistent results. please someone know solution i will be very grateful for their help
the error is: "load combination "all dead load LC " uses linear analysis for a structure that is likely a mat foundation . zero-tension iteration will not be performed so the analysis results will be inaccurate if tension occurs"

Each combination is either linear or zero-tension. The program expects zero-tension type combos when there are area springs supporting the slab.
