The Interference Effect And The Wind Vibration Response Research Of The High-rise Buildings

Through extensive literature and combined with engineering application,this paper expounds the wind load of tall buildings may cause several kind of adverse effects.By investigating the related research results,summarizes the existing research work which are mainly for the research for numerical simulation of the effect of interference,the wind tunnel test and in-situ test method.Due to the limitations of the workload,the computational complexity and the experimental conditions,the research work in the above research work is more simple and contains a number of buildings with a small number of high-rise buildings as the research object.Therefore its research object and the actual situation of engineering application,there is a big gap which makes promotion and application of research results.In this paper,the research on the interference effect of the high buildings select the six buildings as research object.Where in the selected high-rise buildings in each building has a different cross-sectional shape of the building,irregular layout and a different building heights.In this article,based on certain theoretical premise and the existing experimental and numerical simulation results of the research and the relevant specification,calculate the interference effect of high buildings and the wind vibration's effect using theoretical analysis method.And using the fluid dynamic calculation software FLUENT and ANSYS Workbench platform carry out the one-way fluid structure interaction analysis of the selected high-rise building group of the disturbance effect and wind vibration effect.According to this article research needs and workload and so on,use steady flow field and the transient flow field calculation method,the Calculated results were compared with that based on the above data and theoretical analysis.Compared with the theoretical analysis of premise unable to better reflect the complexity of the high-rise buildings interference effect and wind vibration effect.Existing research results for a simple high-rise buildings is difficult to promote the use to more complex engineering practice by theoretical analysis method.And numerical simulation method can be efficient,convenient and accurately response to high-rise building group interference effects and wind vibration effect of the actual situation.Compared with the wind tunnel test and field test research methods,it can be more efficient economic completion of the related research work.The computational fluid dynamics and one way fluid solid coupling method used in this paper can be used to study the disturbance effect and wind induced vibration of high rise buildings.
