後流中における高層建物の動的挙動

Abstract

A wind tunnel experiment was performed to investigate the interaction effect betweenneighboring tall buildings in a boundary layer. Extensive wind tunnel studies of the interac-tion between two similar size structures were reported in previous publications. The increas-ed response and its possible aerodynamic mechanism of a tall rectangular building under theinterference excitation of several types of upwind buildings with different widths have beeninvestigated in the paper.The main results are as follows; 1) The increase in maximum response caused by an up-wind building of smaller size could be 20 times as high as the cross-wind response of isolat-ed building. 2) The along wind response found to be increased with the size of upwindbuildings.
