| چکیده | ||
| This study conducts a numerical investigation into the seismic behavior of trapezoidally corrugated steel plate shear walls (CSPSWs) with openings, evaluating the effects of stiffeners and corrugation orientation (vertical versus horizontal). Finite element models developed in ABAQUS were validated against experimental data, followed by a parametric analysis varying opening number and location, stiffener dimensions, and corrugation direction. Key findings reveal that vertical corrugation outperforms horizontal orientation, enhancing shear capacity by up to 15% and energy dissipation by 20-30%, while horizontal setups exhibit pronounced stress concentrations and reduced ductility. Central openings minimize performance degradation compared to boundary placements, which can reduce capacity by over 10%, and stiffeners around openings yield modest gains (2-4% in strength and absorption) by promoting uniform stress distribution. These results highlight the critical role of optimized configurations in bolstering seismic resilience for high-rise structures in earthquake-prone regions, facilitating material-efficient designs that reduce construction costs, mitigate failure risks, and advance sustainable engineering practices for enhanced structural longevity and safety. | ||
