Numeriacal Simulation Of Wind Pressure And Wind Induced Vibration Of High-Rise Building

In recent years, wind load as a typical dynamic load on building structures catches more and more attention with the developing high-rise buildings and supper high-rise buildings. And the more light and flexible structures make the fluid-structure coupling effect more conspicuous. In this paper, grid and flexible structure models are build in the flow with steady and transient analysis, considering the interaction between flow and structure which has the wind-induced deformation. So it would be more accurate to reflect the structural vibration in the flow.The main contents are included as follows:Firstly, being based on CFX, this paper simulates grid CAARC model in the flow with different wind directions and different turbulence models. And it analysis the results compared with the experimental values.Secondly, being based on CFX, this paper simulates grid high-rise buildings model in the flow with different inlet velocities in steady-state and transient analysis. And it has compared the wind pressure distribution and vortex shedding simulation focusing on researching structural cross-wind vibration and analyzed the lift schedule at different height.Thirdly, based on ANSYS Workbench, this paper builds the analysis platform for elastic high-rise building model in the flow by one-way FSI and two-way FSI methods both using ANSYS transient analysis module and CFX flow analysis module. And it simulates and analyzes the pressure on structural faces, the flow situation and the structural vibration.
