Abstract: In order to standardize the methods, facilities and test report formation of wind tunnel test, Standard for wind tunnel test of buildings and structures was compiled to ensure the reasonable and reliable wind tunnel test result. Investigation was carried out on simulation of atmospheric boundary layer, test similarity, performance of wind tunnel facilities, test method and procedure of wind load and wind environment, data analysis, test report, and so on. All related provisions were provided in the standard. According to the standard, the proposed wind directional factor shall be not less than 0.85 based on the given wind load from wind tunnel test report, and the wind load shall not be less than 70% of that calculated by Load code for the design of building structures（GB 50009—2012）for main structures, and 80% for claddings. In the standard, wind environment assessment method was proposed based on exceedance probability and the number of exceedance, and the human comfort was classified to 5 categories.

Keywords: construction engineering; wind tunnel test; wind tunnel facility; wind load; wind environment
