Product Overview
In this project, a moment-resisting connection with reduced beam section (RBS) 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 article. The Abaqus results are compared with the experimental results to evaluate the accuracy of the numerical model.
Model Description
The model represents a moment-resisting connection with RBS subjected to cyclic loading.
As you observe in the picture, this model is composed of an RBS beam, column, continuity 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
In this model, cyclic loading is applied to the beam according to the loading procedure 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.
Moment–Rotation Response
The moment–rotation response of the connection is obtained from the Abaqus results after performing the cyclic analysis.
The numerical results are extracted and processed to obtain the Moment–Rotation diagram of the connection.
Experimental Validation
The Moment–Rotation diagram obtained from Abaqus is compared with the experimental results reported in the reference article.
This comparison is used to evaluate the ability of the numerical model to reproduce the behavior of the experimental 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.
