Buckling of a honeycomb damper under cyclic loading Abaqus

Product Overview

In this project, we simulate a Honeycomb Structural Fuse (HSF) under cyclic loading in Abaqus.

The Honeycomb Structural Fuse is a metallic damper designed to dissipate earthquake energy through the plastic deformation of its web in shear, while the flanges remain mainly elastic.

The numerical model is developed based on an experimental study to investigate the hysteretic behavior, deformation, and buckling response of the honeycomb structural fuse.

Honeycomb Structural Fuse

The honeycomb configuration is designed to promote shear yielding of the web, allowing the device to dissipate earthquake energy through plastic deformation while the flanges remain mainly elastic.

Different honeycomb geometries can be used to adjust the structural response of the fuse, including its stiffness, strength, deformation capacity, and buckling behavior.

Laboratory Sample

In this picture, you can observe the laboratory sample of the honeycomb damper used in the experimental study.

In this project, the A0.7R3C2 specimen is modeled in Abaqus based on the experimental test.

Cyclic Loading

In this analysis, cyclic loading is applied to the honeycomb damper to investigate its behavior under repeated loading and unloading cycles.

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

Buckling of the Honeycomb Damper

The main objective of this project is to investigate the buckling behavior of the honeycomb damper under cyclic loading.

The honeycomb geometry affects the deformation and buckling behavior of the fuse. In this project, the A0.7R3C2 specimen is modeled in Abaqus to investigate its buckling response under cyclic loading.

The deformation and buckling response obtained from the Abaqus model can be used to evaluate the behavior of the metallic damper during cyclic loading.

Force-Drift Hysteresis Diagram

After performing the cyclic analysis, the force-drift hysteresis diagram is obtained from the Abaqus results.

The hysteresis diagram is then compared with the results obtained from the experimental sample.

Energy Dissipation

The Honeycomb Structural Fuse dissipates earthquake energy through the plastic deformation of its web under cyclic loading.

The resulting force–drift hysteresis response represents the energy dissipated by the fuse during repeated loading cycles.

The Abaqus results can therefore be used to evaluate the energy dissipation behavior of the Honeycomb Structural Fuse under cyclic loading.

Comparison of Abaqus and Experimental Results

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

This comparison is used to evaluate the accuracy of the numerical model and its ability to reproduce the experimental response of the honeycomb damper.

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 behavior of the honeycomb damper under cyclic loading.
