Wind-induced vibrations pose significant challenges to the structural integrity and serviceability of high-rise buildings and large-span structures. While static wind load assessments are well-established, the absence of a universally recognized vibration intensity scale limits the ability to systematically evaluate and compare structural responses. This study proposes the development of a standardized Wind-Induced Vibration Intensity Level (WIVIL pronounced “WeFeel”) through time-history dynamic finite element analysis. Simulations are conducted to analyze displacement, acceleration, and frequency responses under various wind conditions, establishing quantitative vibration thresholds. The proposed WIVIL categorizes vibration levels based on structural performance and human comfort criteria, providing a practical metric for assessing dynamic behavior. Furthermore, WIVIL is designed to support the evaluation of existing structures’ integrity, inform condition-based maintenance strategies, and guide serviceability assessments. The findings offer engineers a practical framework to assess wind-induced vibration risks, enhance the design of wind-resilient structures, and optimize monitoring strategies. Integrating WIVIL into future building codes and structural standards can significantly advance wind resilience, ensuring safer and more efficient built environments.
