Abstract
Shear panel dampers (SPDs) are garnering increasing attention due to their potential to enhance structural safety by effectively mitigating the adverse effects of earthquake and wind loading. However, the absence of a systematic classification method and standardized evaluation criteria for assessing the performance of various types of SPDs across different aspects complicates the selection of the appropriate damper type for practical applications. This paper categorizes SPDs based on structural and material characteristics, such as web configurations, buckling restraint types, and material compositions, providing a comprehensive literature review and systematically summarizing current progress and findings. Building on this comprehensive literature review, a robust evaluation approach is proposed, employing a multi-attribute weighting method to quantitatively evaluate various SPDs in terms of mechanical performance, structural characteristics, manufacturability, and other critical attributes. The results indicate that the proposed evaluation method yields reliable assessment outcomes, enabling decision-makers to clearly identify the advantages and limitations of each SPD type. This approach provides a convenient and dependable framework for selecting damper types in practical applications.
