Abstract：In this paper,according to the wind load calculation method the load code for the design of building structure (GB50009-2012) provided，combining with GB50009-2001(2006 edition)，characteristic value of wind load was analyzed. theoritic explorations were separately from the main stress structure aspect and retaining structure aspect. The effects of various factors，such as dynamic response factor and shape factor, on the characteristic value of wind load were analyzed. The conclusions are valuable to the engineering application．

Keywords：characteristic value of wind load; parameter  β_z ; parameter μ_s
