Vibration and Wave Propagation in High-Rise Industrial Buildings

Investigations and conclusions. In the Guangdong–Hong Kong–Macao Greater Bay Area, several high-rise industrial buildings exceeding 100 meters in height are under construction. These structures uniquely combine industrial production facilities and office spaces within a single architectural entity. This study investigates the vibration-related comfort challenges arising from the transmission of vibrational waves across different sections of these towering complexes. Using a real-world, under-construction high-rise industrial building as a reference, a detailed structural model was developed with advanced finite-element software. Human-induced vibratory loads were applied on a designated floor, and the resulting vibration time-history data were analyzed to understand wave propagation characteristics. To validate the model’s accuracy, a combination of on-site experimental tests and theoretical calculations was conducted. Vibration-time-history data were extracted from a specific building level and analyzed in both the time and frequency domains. Comparative examination of experimental results, theoretical computations, and finite-element simulations confirmed the precision of the finite-element model. The study concludes that vibration-wave propagation in high-rise industrial structures follows a discernible pattern, and a linear regression equation encapsulating these dynamics was formulated.
