Product Overview
In this project, the cyclic behavior of a beam-column joint is simulated in Abaqus based on Specimen S1 from the reference experimental study.
The beam-column joint consists of a wide-flange beam, a square tube column, a panel zone, and a through diaphragm. The specimen was designed to develop a panel yielding dominated mode, with the panel zone providing the main contribution to the inelastic response and energy dissipation of the joint.
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.
Model Description
The model represents a beam-column joint subjected to cyclic loading. The main components of the model include the beam, column, panel, and diaphragm.
The geometry and configuration of the model are defined according to the information provided in the reference experimental study. The required material properties, interactions, boundary conditions, and analysis settings are defined in Abaqus.
The numerical model is developed to reproduce the behavior of the experimental beam-column joint under cyclic loading.
Cyclic Loading
A cyclic loading is applied to the top of the column to investigate the behavior of the beam-column joint under repeated loading and unloading cycles.
The loading history is defined using the Amplitude option in Abaqus based on the loading protocol used in the experimental study.
The structural response is recorded throughout the nonlinear analysis to obtain the hysteretic behavior of the beam-column joint.
Hysteresis Response
The numerical results obtained from Abaqus are used to generate the Moment–Drift hysteresis diagram of the beam-column joint.
The numerical hysteresis response is compared with the experimental results reported in the reference paper.
The hysteresis response of Specimen S1 exhibited a very stable hysteretic behavior during cyclic loading, with no significant strength deterioration. The panel zone developed full and stable hysteresis loops with significant plastic deformation, while the beam experienced only slight plastic deformation. In contrast, the columns remained generally elastic throughout the cyclic loading. This behavior indicates that the panel zone provided the dominant contribution to the inelastic response and energy dissipation of the joint, consistent with the panel yielding dominated mode identified for Specimen S1.
The comparison shows good agreement between the Abaqus results and the experimental results.
Deformation Under Cyclic Loading
The deformation of the beam-column joint is investigated throughout the cyclic loading analysis. The panel zone develops significant inelastic deformation as the story drift increases, consistent with the panel yielding dominated behavior observed in Specimen S1.
The Abaqus results are used to observe the deformation of the model at different stages of the cyclic loading.
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 Moment–Drift hysteresis response and the overall structural behavior of the beam-column joint under cyclic loading.
The numerical results show good conformity with the experimental results, demonstrating that the Abaqus model can reproduce the main behavior observed in the experimental study.
