Double-HSS link for eccentrically braced frame under cyclic loading Abaqus

Product Overview

In this example, we intend to simulate the Double-HSS link for an eccentrically braced frame under cyclic loading in the Abaqus software.

In the right picture, the laboratory model and in the left picture, the sample having been simulated in the Abaqus software can be observed.

Test Setup

The test setup used in the experimental study is reproduced in the Abaqus model in order to investigate the cyclic behavior of the Double-HSS link.

Model Components

As you observe in this picture, this model is composed of HSS, Gusset Plate, End Plate, and Weld.

Cyclic Loading

In this analysis, a cyclic loading is applied to the model according to the loading protocol used in the experimental study.

The cyclic loading amplitude is defined in Abaqus to reproduce the loading history applied to the laboratory specimen.

Comparison of Abaqus and Experimental Results

In this picture, the Force-Rotation hysteresis diagram obtained from the Abaqus software has been compared with the experimental results.

This comparison is used to evaluate the accuracy of the numerical model in reproducing the cyclic response of the experimental Double-HSS link.

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 experimental study.
