This study examined the nonlinear behavior of double-corrugated steel plate shear walls. Initially, a finite element model incorporating material and geometric nonlinearities (using ANSYS software) was developed and calibrated using experimental results from a previous study by Deng et al. Thin-Walled Structures 181, (2022). A parametric study was then conducted to analyze the impact of the steel plate thickness, corrugation depth, and number of corrugations on the force reaction value. The study revealed a linear relationship between increasing plate thickness and reaction force. Corrugation depth improvements were notable at a depth of 75 mm, whereas strain hardening behavior was observed with one corrugation, transitioning to strain softening with more corrugations, resulting in an increased force reaction. Optimal performance was achieved when the corrugation length and gap between the corrugations were similar.

摘要

This study examined the nonlinear behavior of double-corrugated steel plate shear walls. Initially, a finite element model incorporating material and geometric nonlinearities (using ANSYS software) was developed and calibrated using experimental results from a previous study by Deng et al. Thin-Walled Structures 181, (2022). A parametric study was then conducted to analyze the impact of the steel plate thickness, corrugation depth, and number of corrugations on the force reaction value. The study revealed a linear relationship between increasing plate thickness and reaction force. Corrugation depth improvements were notable at a depth of 75 mm, whereas strain hardening behavior was observed with one corrugation, transitioning to strain softening with more corrugations, resulting in an increased force reaction. Optimal performance was achieved when the corrugation length and gap between the corrugations were similar.
