Product Overview
In this project, we simulate the progressive collapse behavior of a steel moment frame joint with a reduced beam section (RBS) using the Abaqus software.
The beam flanges and web are connected to the column using welded connections. The reduced beam section is introduced in the beam flange away from the column face to move the plastic deformation away from the beam-column connection.
In this project, the WUF-W-RBS-50-130-23 specimen is modeled in Abaqus based on the experimental test.
Model Description
Both ends of the beams are supported using pin supports. The distance between the two supports is 3020 mm, and the length of each beam segment from the column face to the corresponding support is 1190 mm.
The numerical model has been developed according to the configuration reported in the reference article to investigate the progressive collapse behavior of the steel moment frame joint.
Vertical Loading
In this analysis, a vertical load is applied to the top of the column.
Following the application of the vertical loading, the structural response of the steel moment frame joint is investigated.
Force–Displacement Diagram
Following the application of the vertical loading, the Force–Displacement diagram is obtained from the Abaqus results.
The Force–Displacement diagram obtained from the Abaqus software is compared with the experimental results to evaluate the accuracy of the numerical model.
Deformation of the Model
As the vertical displacement increases, the inelastic deformation is mainly concentrated around the reduced beam section (RBS). In this model, the final damage develops in the reduced section rather than directly at the beam-to-column connection.
The deformation pattern is used to investigate the structural response of the joint during the progressive collapse analysis.
Equivalent Plastic Strain (PEEQ)
High plastic strain initially develops in the bottom beam flange within the reduced section and progressively extends with increasing displacement, eventually reaching the beam web.
The PEEQ contour is used to investigate the regions of the steel components where significant plastic deformation occurs during the analysis.
Deformation at the Start and End of the Analysis
As you observe in the picture, the deformation of the model at the start and end of the analysis is displayed.
This comparison provides a clear view of the structural deformation developed during the progressive collapse analysis.
Validation
This project has been validated, which means that the results obtained from the Abaqus software are similar to the results reported in the article.
In other words, this project is based on the reference article and the numerical model has been developed to reproduce the behavior reported in the study.
