Abstract

Codification of wind loads considering wind-induced interference effects is an issue in wind engineering as ever. It is difficult to codify a guideline because of the large number of variables involved. Apart from this difficulty and complexity, generalized and simplified guidelines for structural design wind loads will be useful in estimating approximate structural wind loads on tall buildings in preliminary design. The purpose of this study is to tackle the problem of wind-induced interference effects between two tall buildings to establish a generalized set of guidelines. The interference effects between two buildings were investigated by a series of deliberate wind tunnel tests. Various types of adjacent buildings were considered with breadth and height ratios. To reach critical conclusions being used to improve a design code, design interference factor for extreme base bending moment responses was suggested for the assessment of wind-induced interference effects between two tall buildings.
