Hysteresis analysis of the concentric braced frame Abaqus

Product Overview

In this example, we intend to simulate the hysteresis behavior of a concentric braced frame in the Abaqus software.

As you observe in this picture, this model is composed of beam, column, brace, gusset plate, and angle connection.

Cyclic Loading

In this analysis, a cyclic loading is applied to the model to investigate the hysteretic behavior of the concentric braced frame.

The loading history is defined in Abaqus according to the loading protocol used in the experimental study.

Comparison of Abaqus and Experimental Results

In this picture, the force-drift hysteresis diagram obtained from the Abaqus software is compared with the experimental results.

This comparison is used to evaluate the accuracy of the numerical model and its ability to reproduce the experimental response of the concentric braced frame.

Structural Response

The Abaqus results can be used to investigate the deformation and structural response of the concentric braced frame under cyclic loading.

Validation

This project has been validated, which means that the results obtained from the Abaqus software are similar to the results reported in the article.

In other words, this project is based on the reference article and the numerical model has been developed to reproduce the experimental response of the concentric braced frame.
