Product Overview
In this project, a deep beam-to-column connection 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 structural response observed in the experiment.

Model Description
The model represents a deep beam-to-column connection subjected to cyclic loading. The structural components are modeled according to the configuration and dimensions reported in the reference experimental study.
As you observe in the picture, the distance between the loading point and the center of the column is 6000 mm, and the length of the column is 3500 mm.
The required material properties, interactions, boundary conditions, and analysis settings are defined in Abaqus to reproduce the behavior of the experimental connection.
Cyclic Loading
The deep beam-to-column connection is subjected to cyclic loading according to the loading protocol used in the reference experimental study.
The loading history is defined using the Amplitude option in Abaqus. The structure is analyzed under repeated loading and unloading cycles to investigate its nonlinear response.
The response obtained from the analysis is used to evaluate the hysteretic behavior of the connection.
Results and Hysteresis Response
The Abaqus results are extracted and processed to evaluate the structural response of the deep beam-to-column connection under cyclic loading.
The numerical results are used to obtain the force–displacement hysteresis response of the connection.
The numerical hysteresis response is compared with the experimental results reported in the reference paper.
Deformation Under Cyclic Loading
The deformation of the deep beam-to-column connection is investigated during the cyclic loading analysis.
The Abaqus results allow the deformation and nonlinear behavior of the connection to be observed 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 research paper.
The comparison focuses on the hysteresis response and the overall structural behavior of the deep beam-to-column connection under cyclic loading.
The numerical results show good agreement with the experimental results, demonstrating the ability of the Abaqus model to reproduce the main behavior observed in the experimental study.
As you can see, buckling has occurred in the beam flange in both the laboratory and Abaqus models. This indicates that the numerical model is able to reproduce the buckling behavior observed during the experimental test.
