Abstract: This study assesses the vibration comfort of a steel–concrete composite floor system in a high-rise industrial building under construction in Shenzhen. The assessment focuses on human-induced vibrations. Acceleration time histories were recorded, and spectral analysis was conducted to identify the fundamental frequencies and damping ratios. A finite element model of the industrial building was developed to simulate the vibrational response under identical conditions. Additionally, vibration response calculations were carried out using standard methodologies. The performance of a Tuned Mass Damper (TMD) system was analyzed by comparing experimental, theoretical, and simulated results with standard thresholds. Prior to TMD installation, certain locations did not meet vibration comfort standards, but, following installation, all points were within acceptable limits. These findings demonstrate the TMD’s effectiveness in enhancing vibration comfort.
