Hysteresis analysis of beam-column connection with vertical stiffener Abaqus

Product Overview

In this project, the hysteretic behavior of a beam-column connection with a vertical stiffener is investigated using Abaqus.

The numerical model is developed based on an experimental study, and the Abaqus results are compared with the experimental results to evaluate the accuracy of the numerical model.

Model Description

The model represents a beam-column connection with a vertical stiffener subjected to cyclic loading.

As you observe in this picture, the model is composed of a beam, column, shear plate, and vertical stiffener.

In this model, a continuity plate is not utilized. Instead, a vertical stiffener is used in the connection.

The required material properties, interactions, boundary conditions, and analysis settings are defined in Abaqus to reproduce the behavior of the experimental connection.

Cyclic Loading

A cyclic loading is applied to the end of the beam according to the loading protocol used in the experimental study.

The loading history is defined using the Amplitude option in Abaqus. The connection is then analyzed under repeated loading and unloading cycles.

Results and Hysteresis Response

The Abaqus results are extracted and processed to evaluate the structural response of the connection under cyclic loading.

The resulting response is used to obtain the Displacement–Force hysteresis diagram.

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

Deformation Under Cyclic Loading

The deformation of the model undergoing cyclic loading can be observed from the Abaqus results.

The numerical results allow the deformation and nonlinear behavior of the beam-column connection to be evaluated at different stages of the cyclic loading history.

Experimental Validation

The numerical results obtained from Abaqus are compared with the experimental results reported in the reference article.

The comparison focuses on the Displacement–Force hysteresis response and the overall structural behavior of the beam-column connection under cyclic loading.

This project has been validated, which means that the results obtained from Abaqus are similar to the results reported in the reference article. In other words, this project is based on the experimental study.
