The transiting test method is a new approach for structural wind resistance research. However, traffic on the test road inevitably influences test results. In this study, the symmetrical CAARC standard tall building model was used to investigate the influence of a small vehicle near the test vehicle. A small vehicle was set up as an interference vehicle to drive around the test vehicle under different cases during the test. Results indicate that the mean wind pressure coefficient during the overtaking period is higher than that during the no overtaking period. The enlarged relative velocity and the small test vehicle velocity increase the overtaking interference and the data calculation time required to eliminate the overtaking influence. The overtaking influence only occurs if the test vehicle is overtaken by the small vehicle in the adjacent lane. The influence of the overtaking behavior of a small vehicle can be eliminated after the data calculation time exceeds 26 s. Moreover, the wake of small interference vehicle no longer influences the transiting test results after the spacing reaches 24 m.

小型车辆对测量建筑物风压系数的穿越试验方法的影响

过渡试验法是结构抗风研究的一种新方法。但是，测试道路上的交通不可避免地会影响测试结果。在本研究中，采用对称的 CAARC 标准高层建筑模型来研究靠近测试车辆的小型车辆的影响。设置一辆小型车辆作为干扰车辆，在测试过程中在不同情况下绕着测试车辆行驶。结果表明，超车期间的平均风压系数高于不超车期间的平均风压系数。较大的相对速度和较小的试验车速增加了超车干扰和消除超车影响所需的数据计算时间。只有当测试车辆被相邻车道上的小型车辆超车时，才会发生超车影响。数据计算时间超过26 s后，可消除小型车辆超车行为的影响。此外，在间距达到24 m后，小干扰飞行器的尾流不再影响通过测试结果。
