Progressive collapse of two-story by four-bay steel frame Abaqus

Product Overview

In this example, we intend to simulate the progressive collapse of a two-story by four-bay steel frame in the Abaqus software.

The numerical model is developed based on the bare frame configuration reported in the reference study, without masonry infill walls. The analysis investigates the structural response of the steel frame under a center column pushdown scenario.The center column is pushed downward slowly to reduce dynamic effects and simulate a quasi-static loading condition.

Model Description

The steel frame includes HM294 × 200 × 8 × 12 beams and HW350 × 350 × 12 × 19 columns. The structural members are modeled using the material properties reported for Q235 steel in the reference study.

The numerical model is developed according to the configuration reported in the reference article in order to investigate the progressive collapse behavior of the steel frame.

Comparison of Abaqus and Experimental Results

In this picture, the results obtained from the Abaqus software are compared with the reference results.

This comparison is used to evaluate the accuracy of the Abaqus model and its ability to reproduce the behavior of the reference results.

Validation

As you observe, the results obtained from the Abaqus software are concordant with those mentioned in the article.

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.
