Abstract Research purposes: The wind load figuration coefficients of the open sawtooth exoteric surface now always is got through wind tunnel test because the " Load Code for the Design of Building Structures ( GB 5000—2001) " has not correlation content． This paper introduces the research of the wind load figuration coefficients put on the suspension roof of Suzhou and Nanjing South Railway Station through wind tunnel test which are sawtooth exoteric surface． It also discusses the difference with the close roof． Consequently all these work lay a foundation for the structural calculation of next stage．

Research conclusions: ( 1) The wind load pressure figuration coefficients of the open sawtooth exoteric surface now always is about 0． 3 or little 0． 3; ( 2) The wind load suck figuration coefficients is between 0． 3 ～ 0． 6 except little edge region which is 1． 6， the conclusion is close to the "Load Code for the Design of Building Structures ( GB 50009—2001) " ．

Key words： sawtooth surface wind tunnel test figuration coefficients
