Bi-directional hysteretic performance of U-shaped damper Abaqus

Product Overview

In this project, we simulate a U-shaped damper placed at a 45-degree angle under cyclic loading in Abaqus.

The Abaqus model is developed to investigate the bi-directional hysteretic behavior of the U-shaped damper when it is subjected to cyclic deformation in the 45-degree configuration.

The numerical results obtained from Abaqus are compared with the experimental results reported in the reference study to evaluate the ability of the numerical model to reproduce the main hysteretic response of the damper.

In this project, the S3 specimen is modeled in Abaqus based on the experimental test.

Cyclic Loading

In this problem, a cyclic loading is applied to the top of the damper, and its hysteresis diagram is then drawn.

Force–Displacement Hysteresis Diagram

The Force-Displacement hysteresis diagram obtained from the Abaqus software is compared with the laboratory results.

Deformation

In this picture, you can observe the deformation of the model under the cyclic loading.

Validation

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

In other words, this project is based on the reference article.
