a problem in simulating reinforced concrete column in ANSYS

it's always greater than Ex from TB table .! i'm using multilinear curve where modulus of elasticity is always less than the initial EX. 

i've got two problems, the one with the tangent modulus, and the second is that  when a message appears telling me i've got rigid bodt motion .!

i'm including the code, will you check it out and pinpoint the error place ?! i'd be more than gratfull :).

!!! Plain Concrete

!!! LOAD = 27 MPA

!!! Constaint at base = FIX

!!! Crushing elements at the base .!
