RBS moment endplate connection under cyclic loading Abaqus

Product Overview

In this project, an RBS moment end plate connection is modeled in Abaqus and its behavior under cyclic loading is investigated.

The numerical model is developed based on an experimental study. The Abaqus results are compared with the experimental results to evaluate the accuracy of the numerical model and its ability to reproduce the behavior reported in the reference article.

Model Description

The model represents an RBS moment end plate connection subjected to cyclic loading.

As you observe in the picture, this model is composed of an RBS beam, column, continuity plate, bolt, extended end plate, doubler web plate, and stiffener.

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 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 Moment–Rotation hysteresis diagram.

The Moment–Rotation diagram obtained from Abaqus is compared with the experimental 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 numerical results allow the deformation and nonlinear behavior of the RBS moment end plate connection to be evaluated at different stages of the 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 Moment–Rotation response and the overall structural behavior of the RBS moment end plate connection under cyclic loading.

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