    Abstract: In order to gain further understanding of aerodynamic forces and their effects on groups of high-rise buildings, this study used windtunnel experiments. Two square prisms were arranged both in tandem and side-by-side arrangement with different spacings in between. Similar experiments were carried out to study the interactions of aerodynamics between the two prisms when both were stationary, when only one prism oscillated, and finally, when both prisms oscillated. The results showed that the aerodynamic responses were either enhanced or suppressed by the spacing ratios, the oscillating frequencies, and the mutual influences of the two square prisms in various arrangements. The aerodynamics also changed due to the occurrences of different flow patterns, such as channel flow, deflected flow, pulsating flow, and so on. Obviously, the aerodynamics of the flow patterns of the two square prisms in tandem and side-by-side arrangements proved to be more complex than those of a single square prism.
