How to define temperature dependent elasticity for a one dimensional axial type connector in ABAQUS

How to define temperature dependent elasticity for a one dimensional axial type connector in ABAQUS

How to define temperature dependent elasticity for a one dimensional axial type connector in ABAQUS

(OP)
Hi All,

I am trying to model a cold formed steel column incorporating the partial translational restraint given to it by its sheathing. Both spring elements and axial type connector elements suite this purpose and I have used them successfully at ambient temperature. At elevated temperature, only connector elements are suitable for this application. I am encountering a problem with respect to the temperature dependent elastic properties of the connector.

Suppose I define the stiffness of the connector as a fixed value, independent of the temperature. The problem is that the failure time of the column under coupled temp-disp analysis for this case is the same as the failure time I get with temperature dependent connector elastic properties. I believe this is because the CONN3D2 type wire element I use to define the connector does not have temperature degree of freedom. Is there a work around for this problem?

Any help is greatly appreciated.

The average temperature of the two attached nodes is probably used.
