Product Overview
In this project, the Slotted-Web–Reduced-Flange (SWRF) moment connection is modeled in Abaqus and its hysteretic behavior under cyclic loading is investigated.
The numerical model is developed based on the 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 Slotted-Web–Reduced-Flange (SWRF) moment connection subjected to cyclic loading.
As you observe in this picture, this model is composed of an RBS beam, column, continuity plate, and shear plate.
Two slots are created on the web of the beam. The slot geometry is defined according to the configuration of the experimental specimen.
The required material properties, interactions, boundary conditions, and analysis settings are defined in Abaqus to reproduce the behavior of the experimental connection.
Slotted Web Configuration
Two slots are created on the beam web as part of the SWRF connection configuration.
As you observe, the two slots and their shape can be clearly distinguished in the model.
Cyclic Loading
In this problem, cyclic loading is applied to the end of the beam.
The loading history is defined using the Amplitude option in Abaqus. The connection is then subjected to repeated loading and unloading cycles.
The response of the connection under cyclic loading is investigated throughout the nonlinear analysis.
Hysteresis Response
After completing the cyclic analysis, the Abaqus results are extracted to obtain the hysteresis diagram of the connection.
The numerical hysteresis response is then compared with the experimental results reported in the reference article.
Deformation Under Cyclic Loading
The deformation of the model during the cyclic analysis can be observed from the Abaqus results.
The deformation pattern provides additional information about the structural response of the SWRF moment connection under cyclic loading.
Experimental Validation
The numerical results obtained from Abaqus are compared with the experimental results reported in the reference article.
The comparison focuses on the hysteresis response of the 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.
