Product Overview
In this project, a steel plate shear wall (SPSW) is modeled in Abaqus and its behavior under monotonic pushover loading is investigated.
The numerical model is developed based on the 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 steel plate shear wall consisting of two columns, three beams, one steel infill plate, and continuity plates.
The simulated specimen corresponds to the SPSW2 model without stiffeners described in the reference study.
The geometry, 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
The analysis consists of an initial buckling analysis followed by the nonlinear pushover analysis.
First, the buckling modes of the steel plate shear wall are extracted from Abaqus.
The obtained buckling mode is then used to define an initial geometric imperfection in the model. This procedure helps the numerical model better represent the initial imperfections of the experimental specimen.
Pushover Loading
A monotonic loading is applied to the steel plate shear wall to investigate its nonlinear structural response.
The applied load is gradually increased and the corresponding displacement response of the shear wall is recorded throughout the analysis.
The resulting force–displacement response is used to obtain the pushover curve of the structure.
Results and Pushover Response
The Abaqus results are extracted and processed to evaluate the structural response of the steel plate shear wall under monotonic loading.
The force–displacement pushover curve obtained from the numerical analysis is compared with the corresponding results reported in the reference article.
The numerical results show good agreement with the experimental results, demonstrating that the Abaqus model can accurately reproduce the behavior of the investigated shear wall.
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 deformation pattern and the structural response of the steel plate shear wall under monotonic loading.
The deformation obtained from the Abaqus simulation is in good agreement with the deformation observed in the laboratory test.
