Three-story shear wall undergoing a cyclic loading in the Abaqus software

Product Overview

In this project, a three-story steel plate shear wall is modeled in Abaqus and its structural behavior under cyclic loading is investigated.

The Abaqus results are compared with the laboratory results reported in the reference article to evaluate the accuracy of the numerical model.

Model Description

The model represents a three-story steel plate shear wall consisting of two columns, three beams, three steel infill plates, and several stiffeners.

The numerical model is developed according to the configuration described in the reference research article.

The geometry, material properties, interactions, boundary conditions, and analysis settings are defined in Abaqus to reproduce the behavior of the laboratory specimen.

Buckling Analysis and Initial Imperfection

The analysis consists of two main parts: buckling analysis and hysteresis analysis.

First, a buckling analysis is performed to determine the buckling modes of the three-story shear wall.

The obtained buckling modes are then used to define an initial geometric imperfection in the model. This procedure helps the numerical model better represent the initial imperfections of the laboratory specimen.

Cyclic Loading

A cyclic loading is applied to the top beam of the three-story shear wall according to the loading procedure used in the reference study.

The loading history is defined using the Amplitude option in Abaqus. The structure is subjected to repeated loading and unloading cycles to investigate its nonlinear response.

The applied loading and corresponding displacement response are recorded throughout the analysis.

Deformation and Structural Response

The deformation of the three-story shear wall is investigated during the cyclic analysis.

The numerical deformation obtained from Abaqus is compared with the deformation observed in the laboratory specimen.

The comparison provides an indication of the accuracy of the numerical model in reproducing the structural behavior of the tested shear wall.

Results and Hysteresis Response

The Abaqus results are extracted and processed to evaluate the structural response of the three-story shear wall under cyclic loading.

The force–displacement hysteresis curve is obtained from the numerical analysis and compared with the corresponding laboratory results reported in the reference article.

The numerical hysteresis response shows good agreement with the laboratory results, demonstrating the accuracy of the developed Abaqus model.

Experimental Validation

The numerical results obtained from Abaqus are compared with the laboratory results reported in the reference research paper.

The comparison focuses on the deformation and force–displacement hysteresis response of the three-story steel plate shear wall.

The close agreement between the numerical and laboratory results indicates that the developed Abaqus model can properly reproduce the behavior of the investigated shear wall.
