Hysteresis analysis of the steel plate shear wall with partial connection Abaqus

Product Overview

In this project, the hysteresis behavior of a steel plate shear wall with partial connection is investigated using Abaqus.

The numerical model is developed based on the configuration and experimental study reported in the reference paper. The model is subjected to cyclic loading to investigate its nonlinear structural response and hysteretic behavior.

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

Model Description

The model represents a steel plate shear wall with partial connection based on the configuration described in the reference research paper.

In this model, the steel plate is not fully connected to the surrounding structural frame. A partial connection is considered in the numerical model according to the configuration used in the reference study.

The required geometry, material properties, interactions, boundary conditions, and analysis settings are defined in Abaqus to reproduce the structural behavior of the reference model.

Partial Connection

One of the main features of this project is the partial connection of the steel plate to the surrounding frame.

The connected and unconnected portions of the steel plate are defined according to the configuration considered in the reference study.

Buckling Analysis and Initial Imperfection

A buckling analysis is performed to determine the buckling mode of the steel plate shear wall.

The obtained buckling mode is then used to introduce an initial geometric imperfection into the numerical model.

This procedure helps the numerical model reproduce the initial imperfections considered in the structural analysis.

Cyclic Loading

The steel plate shear wall is subjected to cyclic loading according to the loading protocol used in the reference study.

The loading history is defined using the Amplitude option in Abaqus.

The model is then analyzed under repeated loading and unloading cycles to investigate its nonlinear hysteretic response.

Hysteresis Results

The force and displacement results obtained from Abaqus are extracted and processed to obtain the force–displacement hysteresis curve.

The numerical hysteresis response is then compared with the results reported in the reference paper.

Validation

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

The comparison focuses on the force–displacement hysteresis response and the overall structural behavior under cyclic loading.

This comparison is used to evaluate how accurately the numerical model reproduces the behavior reported in the reference study.
