摘 要: 采用高频动态天平技术和气动弹性模型技术对两个形状相同的方形截面高层建筑的顺风向动力干扰效应进行了风洞实验研究 .两种实验方法所得的结果具有良好的一致性 .最后应用人工神经网络方法对试验结果进行了模拟和推广 ,给出了顺风向动力干扰因子的等值线图 。 In this paper,along-wind dynamic interference effects on two tall buildings are researched on the basis of the results of the high-frequency-force-balance test in the TJ-1 wind tunnel laboratory.At the same time,the aeroelastic model test is also used to research on the interference effects with the same configurations,the results of which verify the results of the high-frequency-force-balance test.The artificial neural networks method is used to deal with the experimental data and the along-wind dynamic interference factor( I dx ) contour map is obtained as references for wind load codes.
