Required reinforcement - T shaped column

[RRufino]

Dear all,

Is there any identified issues when calculating T shaped columns on "required reinforcement" module?

I´m calculating the follow column with eurocode 2, concrete C30/37, reinforcement B500c,

As results i get:

For this forces this results are unexpectable. Per instance, using other design software, for the follow reinforcement arrangement (less than 1% for reinforcement ratio),

I got this interaction diagram,

Also, since the Mz should be the conditional one, if on robot i change the T section to a rectangular one (25x85cm2) i get (now Mz should be My):

Thanks in advance,

RR
