Abstract：Referring to test methods of wind tunnel test and field measurement, using wind generated by a moving vehicle, a vehicle-running test method to measure wind pressure coefficients of buildings under ideal road conditions was proposed.Based on theoretical derivation and tests on site, the basic theory of the proposed method was built, the physical test platform for vehicle-running tests was designed and assembled, and the software measurement system was also constructed.The test data processing method was studied and used to measure mean wind pressure coefficients of CAARC standard model’s typical measured points.Effects of different vehicle speeds and repeated tests at the same vehicle speed on mean wind pressure coefficient were analyzed.Results showed that the basic theory of the proposed method is correct; the built hardware and software systems are reasonable; mean wind pressure coefficients of the standard model’s measured points agree well with those of the previous wind tunnel tests published in literature; deviations of repeated test results at the same vehicle speed are small; different vehicle speeds affect mean wind pressure coefficient a little bit; the feasibility of the proposed method under ideal road conditions is verified.
