Problems with identifying the ultimate load of the beam
I am trying to run an analysis of a simple supported reinforced concrete beam in Ansys Workbench 14.5. However, I was not able to identify the ultimate load of the beam. The load-displacement curves don't line up the way I would expect based on the results outcome. From the modelling results, the applied load is directly proportional to the deflection. Do you have an idea? Thank you very much in advance for your help and time.
