X-shaped pipe damper (XPD) under cyclic loading Abaqus

Product Overview

In this example, we intend to simulate the X-shaped Pipe Damper (XPD) under cyclic loading in the Abaqus software.

The X-shaped Pipe Damper (XPD) is a metallic energy dissipation device that is investigated under cyclic loading to evaluate its hysteretic behavior and energy dissipation capacity.

As you observe in this picture, the model includes 2 layers of X-shaped pipe dampers.

Cyclic Loading

In this problem, cyclic loading is applied to the X-shaped Pipe Damper, and its hysteretic behavior is investigated.

The loading history is defined using the corresponding amplitude data in Abaqus.

Force-Displacement Hysteresis Diagram

After applying the cyclic loading, the Force-Displacement hysteresis diagram is obtained from the Abaqus results.

The Force-Displacement hysteresis diagram obtained from Abaqus is compared with the experimental results reported in the reference study.

Deformation of the Damper

The deformation of the X-shaped Pipe Damper under cyclic loading can be observed in the following picture.

Validation

This project has been validated by comparing the numerical results obtained from the Abaqus software with the experimental results reported in the reference article.

The comparison demonstrates the ability of the numerical model to reproduce the hysteretic behavior of the X-shaped Pipe Damper under cyclic loading.
