This study presents a method to predict the critical load of short columns filled with super high
strength concrete with rectangular cross-sections by ANSYS finite element software. In it, the
stress-strain relationship of super-high-strength concrete was considered in the form of
confined compression, and the Drucker-Prager model available in the nonlinear material
library was to conduct a simulation with ANSYS WORKBENCH software. The parameters of
the model in turn are considered individually, the obtained results compare it with the
experimental results published by Xiong (2017). The final results of this study obtained the
effect of the Drucker Prager model parameters on the results of the simulation method with the
experiment. Besides, the simulation results with the parameters of the Drucker-Prager model
are also presented and the error compared with the experiment is not significant. This study
also shows a simpler method than simulation studies for the previous Drucker-Prager model.
