Lower Rebar only to design in Quad Element


i have question regarding design check for rebar in Quad element, im using BEMESS to define rebar layer with multi layer LAY. I try to define D = 0 for upper layer and when i try to run BEMESS CTRL TYPE ULTI, it gives error message.

+++++ error no. 513 in program BLAY_INNER
On every side at least 2 bars must be given for a design in BEMESS.

is there any way to do rebar design on QUAD with only lower rebar?

Thank You

Hello Idham

Have you seen the TEDDY example “symmetric.dat”? Maybe that’s what you’re looking for.
