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.
Model Description
As you observe in this picture, this model is composed of two HSS members, Gusset Plate, End Plate, and Weld.The HSS members are connected to the gusset plate through welded connections
The Double-HSS members form the main active link of the eccentrically braced frame. They are designed to develop plastic deformation and rotation within the link while reducing the forces and demands on the surrounding structural members.
Test Setup
One end of the Double-HSS link was rigidly connected to a column, providing high rotational restraint, while the other end was connected to a rigid L-arm with greater rotational flexibility. The experimental loading condition is reproduced in the Abaqus software to investigate the cyclic behavior of the Double-HSS link.
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.
