This study evaluates the aerodynamic characteristics and lateral displacements of two staggered buildings in a linked-building (LB) system.Particle image velocimetry and pressure measurements are employed, and the lateral displacement is evaluated using a 3-dimensional analytical model.When the gap distance between two non-linked buildings is small, the wind flows in a narrow jet, and a strong suction is generated on the inner surfaces of usc trojans snapback hat the two buildings, leading to a large cross-wind-induced response.However, the cross-wind-induced response is significantly reduced when a link is installed, because the suction forces generated from the buildings are in opposite directions and have a negative aerodynamic correlation.

Conversely, with a large gap distance, the buildings at the front obstruct the wind blowing toward the rear buildings.Therefore, while the pressure distribution, wind-force coefficients, and wind-induced responses of the front and rear buildings show similar trends, the magnitude of impact on the front building is larger than that on princess polly dresses long sleeve the rear building.Installing a link is demonstrated to reduce the wind-induced response of the buildings in an LB system.However, the reduction in the along-wind-induced response is less than that in the cross-wind-induced response when the gap distance is small.
