Product Overview
In this project, the cyclic behavior of a corrugated steel plate shear wall is investigated using Abaqus.
The numerical model is developed based on the experimental study of two-story, single-bay corrugated steel plate shear wall. The model includes the corrugated steel wall panel and steel boundary frame, representing the main structural components of the experimental specimen.
The corrugated geometry increases the lateral stiffness, elastic buckling capacity, and out-of-plane stiffness of the wall panel compared with a conventional flat steel plate shear wall. Under cyclic loading, the corrugated panel can develop shear yielding and inelastic buckling, depending on its corrugation configuration.
The Abaqus model is subjected to cyclic loading to investigate the nonlinear structural response and obtain the force–drift hysteresis response. The numerical results are compared with the experimental results reported in the reference study.
In this project, the HCoSPSW-II specimen is modeled and simulated in Abaqus based on the corresponding experimental study.
Model Description
The model represents a corrugated steel plate shear wall based on the configuration used in the reference experimental study.
The main structural components include the beams and columns, corrugated steel plate, and stiffeners. The corrugated steel plate is arranged with horizontal ribs, following the configuration of the HCoSPSW-II specimen.
The numerical model is developed to investigate the structural response of the corrugated steel plate shear wall under cyclic loading.
Buckling Analysis and Initial Imperfection
The project consists of a buckling analysis followed by a nonlinear hysteresis analysis.
First, a buckling analysis is performed to obtain the buckling modes of the shear wall.
The obtained buckling mode is then used to introduce an initial geometric imperfection into the numerical model.
This procedure allows the numerical model to better represent the initial imperfections of the structural specimen.
Cyclic Loading
The corrugated steel plate shear wall is subjected to cyclic loading applied at the top of the shear wall.
The loading history is defined using the Amplitude option in Abaqus according to the loading protocol used in the reference experimental study.
The structure is analyzed under repeated loading and unloading cycles to investigate its nonlinear hysteretic behavior.
Hysteresis Analysis
Following the cyclic loading analysis, the force and displacement results are extracted from Abaqus to obtain the Force–Drift hysteresis diagram.
The hysteresis response is used to evaluate the nonlinear behavior of the corrugated steel plate shear wall under cyclic loading.
Deformation Under Cyclic Loading
Initially, the corrugated steel panel primarily carries the lateral load through shear load-carrying. As the shear deformation increases, the panel undergoes buckling. At larger displacement levels, tension field action gradually develops and contributes to the lateral load-carrying mechanism.
The numerical deformation pattern provides an additional indication of the structural response and behavior of the shear wall during cyclic loading.
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–Drift hysteresis response and the overall structural behavior under cyclic loading.
The Abaqus results show good agreement with the experimental results, demonstrating the ability of the numerical model to reproduce the behavior of the experimental specimen.
