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

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 steel plate and stiffeners are modeled using S4R shell elements in Abaqus. The slit geometry is modeled according to the configuration of the S4 specimen reported in the reference study.

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

A buckling analysis is performed in Abaqus to obtain the buckling modes of the steel plate and stiffeners.

The first buckling mode is selected to define the initial geometric imperfection of the model.

The initial geometric imperfection is introduced to account for the initial out-of-plane deformation of the specimen and its influence on the cyclic response.

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 Force–Drift hysteresis diagram.

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

Deformation Under Cyclic Loading

The deformation behavior of the S4 specimen is investigated under cyclic loading using the Abaqus results.

The analysis captures the out-of-plane deformation of the steel plate and the flexural-torsional buckling behavior of the specimen. The deformation pattern obtained from Abaqus is compared with the failure mode observed in the experimental test.

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.
