Abstract

Abstract

With the continuous improvement of quality of life， growing attention has been paid to the comfort of living environments. One of the critical factors affecting comfort is floor vibration. When the frequency of a human activity coincides with or approaches the natural frequency of a building floor， resonance occurs， causing the floor’s vibration amplitude to reach its maximum， which can lead to physiological discomfort. Since January 1， 2020， China has officially implemented the Technical Standards for Structural Vibration Comfort of Building Floors （JGJ/T 441-2019）， which is the first specification to systematically summarize the comfort requirements for building floors. This study reviewed existing Chinese and international codes on vibration comfort evaluation. Based on the intended functions of the long-span floors of the Shenzhen Comprehensive Transportation Hub， the MIDAS/Gen software was used to conduct a modal analysis of the more critical areas： the east landscape platform， the east platform， and the west platform. Modal and dynamic response analyses were subsequently performed under single-person and multi-person continuous walking， running， and jumping scenarios. The results showed that when the long-span floors were treated as structures primarily subjected to walking excitation， the first-order vertical natural frequencies of the east landscape platform， east platform， and west platform were all greater than 3 Hz， and their vertical peak accelerations did not exceed 0.15 m/s². Both the frequency and acceleration criteria met the requirements of China’s current specification， confirming that the long-span floors satisfied normal serviceability requirements.
