RAM Concept can calculate punching failure planes and the punching shear stresses due to column reactions (Fz, Mx, My).

RAM Concept is not infallible in its determination of potentially critical sections. For unusual geometries, RAM Concept may not check the appropriate section and / or may check inappropriate sections that give higher than appropriate stress ratios. You should review RAM Concept ’s selections of potentially critical sections and use engineering judgment to decide if RAM Concept ’s selections and the application of the ACI 318 model are appropriate.
