Abstract Research purposes:The No － platform － column Canopy is the open wide building，and steel structure．This paper analyses the results of 14 wind tunnel tests of t No － platform － column Canopy and concludes the commonness．Then contrast with the " Load Code for the Design of Building Structures " ( GB 50009 － 2001) ． This paper educes some distributing of the wind load figuration coefficients of No － platform － column Canopy ． The disciplinarian provide some reference for the structure calculation．
Research conclusions:(1) The wind load pressure figuration coefficients of the No － platform － column Canopy is between 0.1 ～ 0.9，the wind load suck figuration coefficients is between － 0.3 ～ － 2.0; (2) The wind load pressure figuration coefficients of the test is smaller to the " Load Code for the Design of Building Structures" ( GB 50009 － 2001)and the wind load suck figuration coefficients is bigger; (3) The wind load figuration coefficients enlarges on the cornice and hole．
