I am trying to model a steel beam subjected to elevated
temperatures using the ISO834 curve. I'd like to specify the fire coating on
the steel I beam and heat the beam with the coating on it.

The goal is to record the response in terms of displacement with
time, displacement with temperature of the beam.

 I would like to know how do I specify the temperature
increase in the coating over time?

I know I have to use the predefined field in Abaqus, however, do
not know how to specify over time.

 Also, how do I obtain the responses from the results in the
form of tables or graphs?

My aim is also to use a steel grade of Q235, which is usually a
Chinese make. However, I am unable to obtain a table of the stress strain
relationship of the steel grade, where I am only getting figures in published
papers.

Anyone would know where I could get a table of that?

 Thanks for the help
