Abstract

CFDST is an abbreviation that stands for concrete-filled columns that have a dual steel tube. In the past few years, there has been debate on the possibility of using these types of columns. As a consequence of this, the objective of this work is to develop and validate material modeling approaches that are considered to be suitable for use with concrete-filled columns (CFT) that have been exposed to axial compression loads. Using the ABAQUS program as the nonlinear finite element, the suggested models are evaluated by doing a comparison study with the experimental data. This analysis is carried out in order to validate the models. The models are supported by this investigation. In addition, parametric investigations are carried out in order to evaluate the influence that the different strengths of the concrete have on the axial behavior of circular CFDST stub columns. This is done so that a conclusion may be drawn on the significance of the influence.
