Dear Colleagues

 

Could I know why does the moment safety factor for the calculated column equals zero since any concrete section has capacity and there is applied loads ?

 

Kindly ,  take a look to the attached model and capture .

 

Note 01 : this case was occurred in elements  (4787,4788,4793 and 4794).

Note 02 : if you use any capture for explanation . Please send it as attached

The 'basic' value of capacity calculated by Robot is Rd/Sd value and this one should be used as the primary reference..

The other two are sort of informative: what would be the bending capacity for given level of axial force and vice versa. In case of the compression forces being above the critical one there is no 'additional' bending capacity in the column.
