Punching verification of existing slab

Hi,

I am using BEMESS for verification of an existing pile-founded concrete slab. I would like to carry out the punching verification and keep the reinforcement ratio of the longitudinal reinforcement below 0.2 %. I have tried different combinations of PUNCH → RO_V, RO_M and RO_L but BEMESS increase the longitudinal reinforcement beyond the 0,2 %. How can I force BEMESS to keep the longitudinal reinforcement below 0,2 % and instead increase the shear reinforcement?
