Characteristics of Across 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 across wind layer wind force interference characteristic. Distribution of across wind layer wind force and its interference factors with interfering building arranged in different position is considered, fitting formulas describing the characteristic of across wind root mean square(RMS) layer wind force coefficients for side by side and tandem arrangement are obtained. The results show that interfering building probably leads to the across wind mean layer force’s deviation from zero, across wind RMS layer force interference factors can reach up to 2.26.
