Hysteresis analysis of the steel plate shear wall in the Abaqus software

Product Overview

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

The numerical model is developed based on an experimental study 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 consisting of two columns, one steel plate, one beam, and several stiffeners.

The main structural components are modeled according to the configuration used in the reference experimental 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 two main parts: buckling analysis and hysteresis analysis.

First, a buckling analysis is performed to determine the buckling modes of the steel plate shear wall.

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

Cyclic Loading

A cyclic loading is applied to the top part of the shear wall according to the loading protocol used in the experimental study.

The loading history is defined using the Amplitude option in Abaqus. The structure is then subjected to repeated loading and unloading cycles.

The resulting force–displacement response is used to obtain the hysteresis diagram of the steel plate shear wall.

Results and Hysteresis Response

The Abaqus results are extracted and processed to evaluate the structural response of the model under cyclic loading.

The force–displacement hysteresis diagram obtained from the Abaqus analysis is compared with the experimental results reported in the reference article.

The comparison demonstrates how accurately the numerical model reproduces the hysteretic behavior of the experimental specimen.

Experimental Validation

The numerical results obtained from Abaqus are compared with the experimental results reported in the reference research article.

The comparison focuses on the hysteresis response and overall structural behavior of the steel plate shear wall under cyclic loading.

The Abaqus results show close agreement with the experimental results, demonstrating that the developed numerical model can accurately reproduce the behavior reported in the article.
