Does RAM Concept have a cutoff for what it considers a "thick" mat foundation when it designs required reinforcement? I was working on a 5x5x2 spread footing design (no loads) and the preset program minimum reinforcement requirements design rule forces 6#6 each way top and bottom of the footing. Based on ACI 318-19 provisions this is the only location I could find any mention of steel area greater than the minimum flexure/shrinkage of 0.0018Ag.
