Recently the buildings and the structures tend to become taller and larger, however it becomes difficult to keep sufficient stiffness in the context of structural design. Therefore the wind resistant concept is urgently required for the structural safety to the extreme dynamic loading. Although the maximum wind speed for the wind resistant design usually occurs in the case of the typhoon attack in Japan, the aerodynamic nonlinear behaviors of tall buildings and large structures remain unknown under the special conditions that very fluctuating forces are acting due to the typhoon.Here we propose the numerical technique for the analysis of turbulent flows of strong wind like a typhoon. The method is established for the prediction of the wind loading and the response of the tall buildings and large structures.

近年来，建筑和结构趋向于高级化和大型化，但在结构设计中很难保持足够的刚度。因此，为了保证结构在极端动荷载作用下的安全，迫切需要抗风概念。在日本，虽然抗风设计的最大风速通常出现在台风袭击的情况下，但在台风作用非常波动的力的特殊条件下，高层建筑和大型结构的气动非线性行为仍然未知。本文提出了一种分析台风等强风湍流的数值方法。建立了高层建筑和大型结构的风荷载及响应预测方法。
