Analysis of Large Vehicle Interference on Transiting Test for Measuring Building Wind Pressure Coefficient

As a new method for structural wind engineering research, the transiting test has good application prospects. However, in road environment, experimental results will inevitably be influenced by other vehicles (especially larger vehicles). In this paper, large vehicle was set as an interference to drive specific conditions, and symmetrical CAARC standard model used investigate vehicle’s on measuring building pressure coefficient. The indicate that coefficient time history appear clear up down undulation phenomenon during overtaking period instead of single convex phenomenon. mean negative area is lower than no-interference situation. features are easy distinguish, duration long (more 6 s). contrast, when overtaken greater. For following driving, wake no longer interferes with after spacing exceeds 70 m.
