Steel Plate Shear Wall with Coupling under cyclic loading (hysteresis analysis) Abaqus

Product Overview

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

The numerical model is developed based on the experimental study reported in the reference paper. The model consists of columns, beams, RBS beams, coupling beams, HSS members, steel plates, and fins.

Cyclic loading is applied to the top of the shear wall, and the resulting hysteresis response is obtained from the Abaqus analysis.

Model Description

The model represents a steel plate shear wall with coupling based on the configuration used in the reference experimental study.

The main structural components include columns, beams, RBS beams, coupling beams, HSS members, steel plates, and fins.

The geometry, material properties, interactions, boundary conditions, and analysis settings are defined in Abaqus according to the information provided in the reference study.

Buckling Analysis and Initial Imperfection

The project consists of two main analysis stages: buckling analysis and hysteresis analysis.

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

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

This approach helps the numerical model better represent the initial imperfections of the experimental specimen.

Cyclic Loading

Cyclic loading is applied to the top of the shear wall according to the loading protocol used in the reference study.

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

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

Deformation Under Cyclic Loading

The deformation of the shear wall during the cyclic loading analysis is investigated using the Abaqus results.

The numerical results are used to evaluate the deformation pattern and nonlinear response of the coupled shear wall during the loading cycles.

Results and Hysteresis Response

The force and displacement results are extracted from Abaqus after completing the cyclic loading analysis.

These results are processed to obtain the force–displacement hysteresis diagram of the coupled steel plate shear wall.

The hysteresis response provides information about the nonlinear behavior of the structure during repeated loading and unloading cycles.

Experimental Validation

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

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

The Abaqus results show good agreement with the experimental results, demonstrating that the numerical model can reproduce the main hysteretic behavior of the experimental specimen.
