RBS moment connection in box-column under cyclic loading Abaqus

Product Overview

In this project, an RBS moment connection in a box-column is modeled in Abaqus and its behavior under cyclic loading is investigated.

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

Model Description

The model represents an RBS moment connection in a box-column. The main components of the model include the RBS beam, box-column, continuity plate, and stiffener.

The geometry and configuration of the structural components are defined according to the information provided in the reference experimental study. The required material properties, interactions, boundary conditions, and analysis settings are defined in Abaqus.

The numerical model is developed to investigate the behavior of the connection when subjected to repeated cyclic loading.

Cyclic Loading

A cyclic loading is applied to the top of the beam to investigate the behavior of the RBS moment connection under repeated loading and unloading cycles.

The loading history is defined using the Amplitude option in Abaqus based on the loading protocol used in the experimental study.

The resulting response of the connection is used to evaluate its hysteretic behavior under cyclic loading.

Results and Hysteresis Response

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

The Moment–Drift hysteresis diagram obtained from the Abaqus analysis is compared with the experimental results reported in the reference article.

This comparison shows how closely the numerical model reproduces the hysteretic response observed in the experimental study.

Deformation Under Cyclic Loading

The deformation of the numerical model is investigated during the cyclic loading analysis. The Abaqus results can be used to observe the deformation and structural response of the RBS moment connection throughout the loading cycles.

Experimental Validation

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

The comparison focuses on the Moment–Drift hysteresis response of the connection under cyclic loading.

The numerical results show good agreement with the experimental results, demonstrating that the Abaqus model can reproduce the main characteristics of the experimental response.
