Honeycomb Structural Fuse (HSF) | metallic damper under cyclic loading Abaqus

Product Overview

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

The Honeycomb Structural Fuse is a metallic damper designed for seismic applications. It consists of a welded wide-flange section with honeycomb-shaped openings in the web.

The HSF dissipates energy through plastic deformation of the web, while the flanges remain mainly elastic.

The Abaqus model is used to study the cyclic behavior, deformation, and force–drift hysteresis response of Specimen a0.3r3c4. The Abaqus results are compared with the experimental results reported for the same specimen in the reference study.

Laboratory Sample

The experimental specimen a0.3r3c4 was tested under cyclic loading in the reference study. The specimen was used to investigate the hysteretic behavior and deformation of the Honeycomb Structural Fuse.

Cyclic Loading

Honeycomb damper is subjected to displacement-based cyclic loading to investigate the hysteretic behavior of the Honeycomb Structural Fuse.

The cyclic loading history is defined in Abaqus using amplitude data and applied to the model according to the experimental loading protocol.

Force–Drift Hysteresis Diagram

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

In this picture, the Force-Drift hysteresis diagram obtained from Abaqus is compared with the results obtained from the experimental sample.

Deformation of the Model

The deformation of the Honeycomb Structural Fuse under cyclic loading can be observed in the following picture.

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 Structural Fuse under cyclic loading.
