摘要：
Here, taking Taipei 101 Building as the study object, a new turbulent fluctuating flow field generation method named the discretizing and synthesizing random flow generator (DSRFG) was proposed to simulate turbulent inlet boundary conditions of the wind field around Taipei 101 building, and the detached eddy simulation (DES) was used to do numerical wind tunnel tests for the building. According to shape characteristics of the building, a geometric model was established for numerical simulation of wind load of the building. Based on the data of structural modes and natural frequencies obtained using the vibration monitoring system of the building, the structural model of the building was established for aeroelastic response analysis. The calculation results were compared with the corresponding data of field measurement and wind tunnel force tests to verify the effectiveness of the numerical wind tunnel. The equivalent wind load and wind-induced response of the building's numerical model with and without fluid-structure interaction were contrastively analyzed, and influences of fluid-structure interaction effect on the wind flow field around the building were explored. The study results showed that in the downwind direction, the wind-induced response of the building is not easily affected by fluid-structure interaction effect, while in the cross wind direction, the equivalent static wind load, acceleration and displacement responses of the finite element model considering bi-directional fluid-structure interaction are smaller than those of the finite element model without considering fluid-structure interaction; in wind flow field, the fluid-structure interaction effect reduces the vorticity on both sides of the building, but it can produce larger shedding vortex which may cause adverse effects on wind environment of downstream buildings. © 2021, Editorial Office of Journal of Vibration and Shock.
