【Abstract】 This paper proposes a suggestion about statistics of maxium mean wind speed by use of the translation method of extrem distribution based on the closed solution of structural response corresponding to Davenport spectral, a calculation method of structural response under wind load is given. The precise solution of dynamic coefficient wind vibration is obtained and compared with the solution and appoximate solution given in load code of China. The paper also points out the problems in load code of China. Finally, on the base of considering the randomness of resistant force the paper puts forward the method of reliability analysis of structures under wind load.更多还原
