Hi. I'm currently using ANSYS Student and, I want to study the effect of fire on structure. I am using Transient Structural Analysis to get the structure's response but, it stopped from analyzing because it gets a lot of warnings regarding the points on the stress-strain curve of concrete not having the same slope. I used Multilinear Kinematic Hardening to define it so, I get why it had those warnings.

But, still, I want to continue with the analysis.

How would I input a stress-strain curve of concrete with different slopes? What is the method that will allow me to input a decreasing stress (after the f'c) because all methods seem to not accept a negative slope?

Thank you.

Hi,

Please search for a video titled ' ANSYS Tutorial: Nonlinear analysis of Reinforced Concrete Beam and compare with test results' on YouTube and see if it helps.
