When equal number of bars are provided in all columns from plinth to top floors, after design it’s showing lesser bars at the bottom and more at top
RCDC designs the column floor-wise. If percentage reinforcement required at a given level is more than the lower floor then it could be because of higher moment at that floor. Normally this happens at terrace floor where moments are more as compared to lower floors. This can be checked as per efficiency ratios in the design table.
