高层结构抗风分析

采用标准k-ε湍流模型,对处于C类地貌风场中多栋复杂体型高层建筑组成的建筑群通过流体力学计算软件fluent进行风场数值模拟,计算得出了群楼周围的流场分布.群楼模拟同单栋模型结果对比可知,实际工程中相邻建筑的相互干扰对结构受到的风力产生不可忽略的影响.

Study on wind loading of tall structure

The wind induced static interference effects on some tall buildings are numerically simulated by using the CFD （Computational Fluid Dynamics） technology. Through the fluent software to simulate the actual wind complex environment. The flow field are computed using standard k -ε turbulence model in the boundary layer flow with terrain C, and the building group simulating results are compared with a single model,which show that the actual engineering adjacent buildings in mutual interference by the wind to structure be ignored influence.
