Vibrations of a pair of elastically supported tall building models in a uniform stream

Experimental investigations were carried out to examine the flow features around a pair of elastically supported square cylinders and the associated flow-excited vibrations. Square cylinders of finite height were placed side by side in parallel to model adjacent tall buildings. The undisturbed uniform cross stream is along the side of the buildings. The experiment was carried vit in a recirculating water channel. The flow field was visualized using hydrogen bubble technique. Time sequential photography was used to quantify the development of the vortex pattern and the vibrational characteristics of the building models.
