Numerical study of cyclic behavior of single-layer flat-corrugated steel shear walls
摘要
Research has suggested substituting corrugated plates for flat plates to mitigate the adverse effects of buckling in these walls. However, corrugated plates typically result in a reduction in the maximum strength of the system. In this research, the characteristics of a single-layer hybrid system, which combines both flat and corrugated plates in the same plane, have been investigated in comparison to flat and fully corrugated SPSWs. This approach aims to reach the advantages of both plate types. The study employs the finite element method to investigate various configurations, with a focus on different corrugation locations, ratios, and angles. The modeling results indicate that the maximum strength of the hybrid system exceeds that of a fully corrugated wall and, in some cases, is comparable to the strength of a flat steel shear wall. Additionally, configurations with corrugation located in the middle of the hybrid system exhibit higher maximum strength than those with corrugation located elsewhere. The initial stiffness of the proposed hybrid system also exceeds that of traditional flat steel shear walls, with models featuring middle corrugation demonstrating even greater stiffness than fully corrugated shear walls. These findings underscore the efficacy of this new type of steel shear wall system.
