Product Overview
In this project, a corrugated steel plate shear wall (CSPSW) is modeled in Abaqus and its behavior under cyclic loading is investigated.
The numerical model is developed based on a laboratory experimental study. The Abaqus results are compared with the laboratory results to evaluate the accuracy of the numerical model and its ability to reproduce the structural response observed in the experiment.
Model Description
The structural model consists of a beam, column, corrugated steel plate, and stiffener. The geometry and structural configuration are defined according to the information provided in the reference study.
The required material properties, interactions, boundary conditions, and analysis settings are defined in Abaqus to reproduce the behavior of the laboratory specimen.
In this project, the Specimen 1 is modeled in Abaqus based on the experimental test.
Experimental Model
The corrugated geometry of the steel plate significantly influences its buckling behavior by improving out-of-plane stability compared with a conventional flat steel plate. The corrugation pattern changes the deformation mechanism and affects the buckling response of the shear wall under loading.
The experimental configuration is used as the basis for defining the geometry, loading conditions, and structural behavior of the Abaqus model.
Buckling Analysis and Initial Imperfection
The first part of the project consists of a buckling analysis.
Buckling modes are extracted from the Abaqus analysis to investigate the buckling behavior of the corrugated steel plate shear wall.
The obtained buckling modes are then used to define an initial geometric imperfection in the numerical model. This approach helps the model better represent the initial geometric imperfections of the experimental specimen.
Cyclic Loading
After the buckling analysis, the corrugated steel plate shear wall is subjected to cyclic loading.
The cyclic loading is applied to the top of the shear wall according to the loading procedure used in the laboratory experiment.
The loading history is defined using the required amplitude data in Abaqus, and the model is analyzed under repeated loading and unloading cycles.
Deformation Under Cyclic Loading
The deformation of the corrugated steel plate shear wall is evaluated during the cyclic loading analysis.
The numerical results are used to investigate the structural deformation and response of the shear wall under repeated loading.
Results and Hysteresis Response
The Abaqus results are extracted and processed to evaluate the structural response of the corrugated steel plate shear wall.
The Force–Displacement hysteresis diagram obtained from the Abaqus analysis is compared with the corresponding laboratory results.
The comparison demonstrates the ability of the numerical model to reproduce the main characteristics of the experimental cyclic response.
Experimental Validation
The numerical results are compared with the experimental results reported in the reference research paper.
The comparison focuses on the hysteresis response and deformation behavior of the corrugated steel plate shear wall under cyclic loading.
The Abaqus results show good agreement with the laboratory results, confirming the validity of the numerical model for reproducing the structural behavior observed in the experiment.
