Hysteretic behavior of steel plate shear wall with slits Abaqus

Product Overview

In this project, a steel plate shear wall with slits is modeled in Abaqus and its hysteretic behavior under cyclic loading is investigated.

The numerical model consists of a steel plate and two stiffeners. Seven slits are created on the steel plate based on the configuration of the experimental specimen reported in the reference article.

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 steel plate shear wall with slits based on the configuration of the experimental specimen reported in the reference article.

The main structural components are a steel plate and two stiffeners. In addition, seven slits are created on the steel plate.

The required material properties, boundary conditions, loading conditions, and analysis settings are defined in Abaqus to reproduce the behavior of the experimental specimen.

Cyclic Loading

The steel plate shear wall is subjected to cyclic loading applied to the top of the shear wall.

The loading history is defined according to the experimental loading protocol used in the reference study.

The resulting force and drift response is used to evaluate the hysteretic behavior of the steel plate shear wall under repeated loading and unloading cycles.

Buckling Analysis and Initial Imperfection

The first part of the project consists of a buckling analysis of the steel plate shear wall.

Buckling modes are extracted from the Abaqus analysis and are then used to define the initial geometric imperfection of the numerical model.

This approach allows the numerical model to better represent the initial geometric condition of the experimental specimen.

Hysteresis Analysis

The second part of the project consists of the hysteresis analysis of the steel plate shear wall under cyclic loading.

The force and drift data obtained from the Abaqus analysis are extracted and processed to generate the Drift–Force hysteresis diagram.

The numerical hysteresis response is then compared with the experimental response reported in the reference article.

Deformation Under Cyclic Loading

The deformation of the steel plate shear wall during the cyclic loading analysis can be observed from the Abaqus results.

The numerical results provide information about the deformation pattern and structural response of the shear wall throughout the loading cycles.

Experimental Validation

This project has been validated against the experimental results reported in the reference article.

The numerical results obtained from Abaqus are compared with the experimental results to evaluate the accuracy of the numerical model.

The comparison shows that the Abaqus results are similar to the results reported in the article.
