Abstract

Here, to systematically study wind load distribution mode and time-varying characteristics of a 180 m-high 3-tube cluster steel chimney, a certain 180 m-high 3-tube cluster steel chimney under construction in our country was taken as the study object. Firstly, through wind tunnel tests of synchronous rigid body pressure measurement, average and fluctuating wind loads on surface of each exhaust pipe of the 3-tube cluster steel chimney under different wind direction angles were obtained. On this basis, distribution laws of mean wind pressure, fluctuating wind pressure, lift coefficient, drag coefficient and overall average shape coefficient on surface of 3 exhaust pipes of the 3-tube cluster steel chimney under typical wind direction angle were contrastively analyzed. Gauss and non-Gauss distributions and time-varying characteristics of wind pressure signals were discussed, correlations of wind pressure signals in time domain and space domain were concluded, and influence laws of wind direction angle and inference effect on aerodynamic force distribution of the 3-tube cluster chimney system were summarized. The study showed that the interference effect of wind load on the 3-tube cluster chimney system mainly is shielding effect, and the maximum overall shape coefficient is 0.71; under wind direction angles of 0°, 90° and 180°, 59.9%, 53.4% and 56.9% of wind pressure signals reveal characteristics of large deflection and high-peak distribution; the main study conclusions can provide a scientific basis for wind load values of multi-tube cluster steel chimney.
