Cyclic test of a coupled steel plate shear wall (hysteresis analysis) Abaqus

Product Overview

In this project, a coupled steel plate shear wall (C-SPSW) is modeled in Abaqus and its behavior under cyclic loading is investigated. The numerical model is developed based on an experimental study reported in the reference paper.

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 coupled steel plate shear wall based on the configuration used in the reference experimental study. The model represents a multi-story coupled steel plate shear wall system consisting of steel infill plates, boundary beams, boundary columns, and coupling beams. The numerical analysis focuses on the cyclic lateral response and overturning behavior of the C-SPSW specimen.

The infill plates are modeled using 3.5 mm thick low-yield-strength steel, while the boundary elements and coupling beams are modeled using A572 Grade 50 steel.

The coupling beams provide interaction between the individual wall panels and allow the C-SPSW system to act as an integrated structural system.

The required 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

A buckling analysis is first performed to determine the buckling mode of the structure.

The obtained buckling mode is then used to introduce an initial geometric imperfection into the model. This approach helps the numerical model better represent the initial imperfections of the experimental specimen.

Cyclic Loading

The C-SPSW model is subjected to cyclic lateral loading in Abaqus to reproduce the loading procedure used in the experimental study. The loading is applied through a displacement-controlled loading protocol with increasing drift levels.

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

The resulting force–displacement response is used to obtain the hysteresis curve of the structure.

Results and Hysteresis Response

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

The force–drift hysteresis curve obtained from the numerical model is compared with the experimental curve reported in the reference paper.

This comparison shows how closely the Abaqus model reproduces the behavior of the experimental specimen.

Experimental Validation

The numerical results are compared with the experimental results reported in the reference research paper.

The comparison focuses on the force–drift response and overall structural behavior under cyclic loading. The numerical results show good agreement with the experimental results.
