Simulation of bare frame under cyclic loading in Abaqus

Product Overview

In this example, we intend to simulate a bare frame under cyclic loading in the Abaqus software.

Model Description

As you observe in the picture, this model is composed of beam, column, stiffener, box, and connecting plate.

The numerical model has been developed according to the configuration reported in the reference article in order to investigate the cyclic behavior of the bare frame.

Cyclic Loading

In this analysis, a cyclic loading is applied to the top of the model.

The cyclic loading amplitude is defined in Abaqus according to the loading protocol used in the reference study.

Comparison of Abaqus and Experimental Results

In this picture, the force-displacement 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 in reproducing the cyclic behavior of the experimental frame.

Deformation of the Bare Frame

As shown in the picture, the deformation of the bare frame undergoing cyclic loading can be observed from the Abaqus results.

The deformation pattern is used to investigate the structural response of the frame during the cyclic loading analysis.

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 cyclic behavior reported in the study.
