| Abstract: | The interest in the time-domain calculations of structural response has intensified with the progress of computational techniques.Based on the theory of stochastic vibration and the Chinese wind loading codes,the coefficient K in the expression of Davenport spectrum is formularized in this paper.The establishment of the relation between coefficient K and Roughness exponent assures the reliability and normalization of the structural response to wind excitation calculated by time-domain method,which provides the application of the time-domain method to wind engineering with great convenience. |
