Product Overview
In this project, a coupled steel plate shear wall (CSPSW) 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 coupled steel plate shear wall based on the configuration used in the reference experimental study. The main structural components are modeled according to the dimensions and information provided in the paper.
The required material properties, interactions, boundary conditions, and analysis settings are defined in Abaqus to reproduce the behavior of the experimental specimen.
Buckling Analysis and Initial Imperfection
A buckling analysis is first performed to determine the buckling mode of the structure.
The obtained buckling mode is then used to introduce an initial geometric imperfection into the model. This approach helps the numerical model better represent the initial imperfections of the experimental specimen.
Cyclic Loading
The model is subjected to cyclic loading based on the loading protocol used in the reference paper.
The loading history is defined using the Amplitude option in Abaqus. The structure is then analyzed under repeated loading and unloading cycles.
The resulting force–displacement response is used to obtain the hysteresis curve of the structure.
Results and Hysteresis Response
The Abaqus results are extracted and processed to evaluate the structural response under cyclic loading.
The force–displacement hysteresis curve obtained from the numerical model is compared with the experimental curve reported in the reference paper.
This comparison shows how closely the Abaqus model reproduces the behavior of the experimental specimen.
Experimental Validation
The numerical results are compared with the experimental results reported in the reference research paper.
The comparison focuses on the force–displacement response and overall structural behavior under cyclic loading. The numerical results show good agreement with the experimental results.
