Abstract

In recent few years, it has become well known that a strong wind blows around a high rise building. Now it is an important problem, for designers, users of the building and inhabitants near the building, how to estimate the speed and the area of the strong wind around the building and how to protect pedestrians and shops from the strong wind. The strong wind which occurs around a single building was studied in the preceding report, Part I. In this report, Part II, it is investigated how the strong wind occurs around arrangements made up of several buildings and how the strong wind can be sheltered by a windbreak, using the wind tunnel technique. The arrangements are made up of simple block-shaped models which are same as that used in Part I. The types of the arrangement are the end to end arrangement, the exploded L-shaped arrangement, the face to face arrangement, the exploded U-shaped arrangement and the exploded H-shaped arrangement. In the case of the end to end arrangement, the strong wind occurs in the opening of the models, which is similar to the strong wind through the pilotis of a single block-shaped model. When the opening is narrow, the wind increasing ratio becomes 1.6. This value is much lager than value 1.2〜1.3 which occurs at the corner of the single model. In all types of the arrangement, the strong wind occurs in the opening of models and at the corner of models. But the increasing ratio in the opening is a little larger than that at the corner.
