Distribution of Wind Pressure on Claddings of Apartment Buildings Affected by Neighboring Buildings

This paper presents wind pressure distribution on high-rise apartment buildings through wind-tunnel tests. In order to investigate wind-induced interference efforts on building claddings an apartment complex, which was damaged on the claddings during typhoon attack, was exampled and constructed as a scaled model. A series of wind tunnel tests using pressure models were performed in a boundary layer wind tunnel. The test results with and without interfering buildings were compared and discussed. It is observed that the wind pressure on buildings 105 and 106 with surrounding buildings shows highly negative, while the pressure without surrounding buildings were positive. Therefore the wind-induced interference effects should be taken into account in the design of claddings through wind-tunnel tests.
