Characteristics of Along wind Layer Wind Force Interference Effect of Two Square Tall Buildings

Abstract:

Layer wind force interference characteristic of disturbed building is studied by rigid model pressure test, and this paper presents the along wind layer wind force interference characteristic. A study is made of the distribution of along wind layer wind force and its interference factors by arranging interfering building in different positions. The fitting formulas describing the characteristic of along wind mean layer wind force interference factors for side by side and tandem arrangement are obtained. The results show that the distribution laws of layer wind force and layer wind force interference factors change with the position of the interfering building. Maximum interference factors of along wind mean layer wind force and root mean square(RMS) layer wind force are found to be 1.08 and above 1.5 respectively.
