Wind Tunnel Test And Analysis Of Sichuan Investment Group Office Tower

In China, tall building have been greatly developed in the recent years and many complex-shape buildings are coming forth. But only several shape coefficients of simple buidings can be refered to the load codes and obtaining the wind loads on the comlplex-shape buildings are suggested to have wind runnel tests in the codes. By means of the combination of wind tunnel test and numerical simulation, wind loads on the complex-shape building, Sichuan Investment Group Office Tower, are analyzed in this paper, which include the following main points:â‘ The design of model and the blue print of wind runnel test are carried on. Aimed at the difficulty on locations of pressure points on the surface of complex shape buildings, the distributions of wind pressure on buildings are estimated by means of numerical simulation before wind tunnel tests, and then it is realized to optimize the locations of pressure points.â‘¡The experiment of measuring wind pressure on the surface of Sichuan Investment Group Office Tower is carried out in the boundary layer wind tunnel (BLWT). Based on the experiment data, the characteristics of the wind load distribution on the surface of the building is obtained, which is under the different conditions, such as various wind directions, different terrain. The max(min) wind pressure values of once for 50(100) years are also calculated.â‘¢Based on the software of Fluent6.1, the model is built reasonablely and calculated. The practices show that numerical simulation not only optimizes the location of pressure points before the experiment, but also distinguishs the data truth or not during the experiment, and its results can be compared with the experiment data after the experiment. So it makes the experiment go on more efficiently. Meanwhile, as the results of numeral simulation have a good meet with the experiment data, the contours of wind pressure are valuable for design.
