R/C column modeling using ANSYS and loading rate and mesh method influence studies

Abstract

Many times, either the research engineer or the design engineer needs to model reinforced concrete (R/C) structural elements in order to study their behavior. In the present research work, an attempt is made to study the correct way of modeling a reinforced concrete column using the finite element ANSYS software. Three-dimensional finite elements are used to model the column. The results of the column modeling and analysis using ANSYS software are compared with the corresponding experimental results of a column with the same geometric characteristics and the same material and load properties as those of the analytical modeling. The only difference between the analytical column modeling and the experimental specimen is the difference in the loading rate. The analytical and experimental results are compared with each other. The influence of the loading rate as well as the mesh method is examined. Useful conclusions are drawn regarding the influence of the loading rate and the mesh method on the behavior and results of reinforced concrete components.
