Product Overview
In this project, the connection of a beam to a column using top and bottom flange plates 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 beam-to-column connection using top and bottom flange plates.
The main components of the numerical model include the beam, column, top flange plate, bottom flange plate, shear plate, continuity plate, and weld.
The geometry and configuration of the structural components are defined according to the experimental specimen reported in the reference study. The required material properties, interactions, boundary conditions, and analysis settings are then defined in Abaqus to reproduce the behavior of the experimental connection.
Connection Components
The numerical model consists of several structural components that work together to represent the experimental connection.
- Beam – the main structural member subjected to cyclic loading.
- Column – the supporting structural member.
- Top Flange Plate – connects the upper flange region of the beam to the column.
- Bottom Flange Plate – connects the lower flange region of the beam to the column.
- Shear Plate – transfers shear between the beam and column.
- Continuity Plate – provides additional reinforcement in the connection region.
- Weld – represents the welded connection between the structural components.
Cyclic Loading
A cyclic loading is applied to the end of the beam to investigate the behavior of the connection under repeated loading and unloading cycles.
The loading history is defined using the Amplitude option in Abaqus according to the loading protocol used in the experimental study.
The resulting force and displacement response is used to obtain the hysteresis behavior of the beam-to-column connection.
Deformation and Structural Response
The deformation of the connection is investigated throughout the cyclic loading analysis.
The Abaqus results allow the deformation and nonlinear response of the beam-to-column connection and its structural components to be evaluated under cyclic loading.
Results and Hysteresis Response
The Abaqus results are extracted and processed to evaluate the structural response of the connection under cyclic loading.
The drift–moment hysteresis diagram obtained from the Abaqus analysis is compared with the experimental results reported in the reference article.
This comparison is used to evaluate how accurately the numerical model reproduces the hysteretic behavior observed in the experimental test.
Experimental Validation
The numerical results obtained from Abaqus are compared with the experimental results reported in the reference research article.
The comparison focuses on the drift–moment hysteresis response and the overall structural behavior of the beam-to-column connection under cyclic loading.
The results obtained from the Abaqus model are similar to the experimental results, demonstrating that the numerical model can reproduce the main characteristics of the tested connection.
