Abstract

Abstract

The wind-induced effect is one of the important control factors of chimney in design. A chimney with rectangular section (about 100 meters high) located in Wuhan is decorated with fishscale surface, which can not only play a decorative effect, but also restrain its wind load. In addition, an adjacent factory building (about 50 meters high) will also have a significant aerodynamic interference effect on the chimney. Therefore, the wind load (shape factor) and wind-induced response (equivalent static wind load) of the chimney were studied by means of wind tunnel test of rigid model for pressures measured. The research showed that: the fishscale treatment could significantly reduce the windward wind load (shape factor) and the across-wind vortex shedding effect of the chimney; the aerodynamic interference effect of the nearby factory building on the chimney was very obvious: when it was located in the upstream, the wind pressure on the windward side of the chimney became negative; when it was located in the downstream, the negative pressure on the crosswind side of the chimney became positive pressure, when it was located in one side, the negative pressure on the crosswind side near the factory building became larger, and even the windward side became negative pressure due to the influence of the separated flow and vortex shedding of the factory building; the along-wind equivalent static wind load based on CQC inversion method was close to that of Load Code for the Design of Building Structures (GB 5009—2012), while that of across wind and torsion direction were quite different.
