Cyclic test of concrete-filled steel box column Abaqus

Project Overview

In this Abaqus project, the behavior of a concrete-filled steel box column under cyclic loading is simulated and investigated.

The numerical results obtained from Abaqus are compared with experimental results to evaluate the accuracy of the numerical model. The simulation is based on a research article and has been validated against the corresponding experimental results.

Model Configuration

The model consists of a steel column, top concrete, a diaphragm, a bottom column, and a rib..

As shown in the figure, the top concrete and bottom concrete are separated from each other by a diaphragm. This configuration allows the structural behavior of the concrete-filled steel box column to be investigated under cyclic loading.

Cyclic Loading

Cyclic loading is applied to the model to investigate its structural response under repeated loading and unloading cycles. The loading history is defined according to the experimental configuration used in the reference study.

The loading amplitude used in the simulation is also provided as an Excel file, allowing the loading history to be examined and reused with the numerical model.

Comparison with Experimental Results

One of the main objectives of this project is to compare the numerical results obtained from Abaqus with the results of the experimental test.

As shown in the figure, the Abaqus results show good agreement with the experimental results. This comparison demonstrates that the numerical model can reproduce the main structural response observed in the experimental specimen.

Hysteresis Curve

The cyclic response of the column is evaluated using the hysteresis curve obtained from the Abaqus analysis.

The numerical hysteresis curve is compared with the corresponding results reported in the reference article. The comparison provides a useful way to evaluate the ability of the numerical model to reproduce the cyclic behavior of the concrete-filled steel box column.

Validation of the Numerical Model

This project has been validated by comparing the numerical results obtained from Abaqus with the experimental and published results. The good agreement between the results indicates that the model can effectively reproduce the cyclic response of the tested concrete-filled steel box column.

The project is based on a research article and provides both the numerical model and the reference paper used for validation.
