If we have a series of columns as shown in the picture below and to reduce deflection of the slab between two columns that are 11.7 m apart we placed a drop beam 30 x 100 cm (the slab is 35 cm thick) do we need to check the punching shear for these two columns ? and if we need to check the punching shear do we use the beam thickness (100 cm) or we use the slab thickness (35 cm)

I am asking this particular question because in SAFE for columns C5 through C12 does calculate the punching shear

Do we need to check punching shear when a drop beam is connecting columns?
