Seismic performance of steel beam to column connection with tapered beam flange Abaqus

Product Overview

In this project, the seismic performance of a steel beam-to-column connection with a tapered beam flange is investigated using Abaqus.

The numerical model is developed based on the experimental study reported in the reference article. The Abaqus results are compared with the laboratory results to evaluate the accuracy of the numerical model.

Model Description

The model represents a steel beam-to-column connection with a tapered beam flange.

As you observe in this picture, the model is composed of a link beam, stub beam, column, and two continuity plates which have been placed inside the column.

The geometry of the structural components is defined according to the configuration of the experimental specimen reported in the reference article.

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

Connection Components

The connection includes a link beam, stub beam, column, and two continuity plates located inside the column.

The continuity plates are modeled according to the configuration of the experimental connection to properly represent the structural behavior of the joint.

Cyclic Loading

In this problem, cyclic loading is applied to the end of the beam.

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

The structural response of the connection is investigated throughout the nonlinear cyclic analysis.

Hysteresis Response

After completing the cyclic analysis, the Abaqus results are extracted to obtain the force–displacement hysteresis diagram of the connection.

The numerical hysteresis response is compared with the laboratory results reported in the reference article.

Deformation Under Cyclic Loading

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

The deformation pattern provides information about the structural response of the connection during the cyclic analysis.

Experimental Validation

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

The comparison focuses on the force–displacement hysteresis response of the 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 article. In other words, this project is based on the experimental study.
