Study of Properties of Phase Spectrum and Phase Difference Spectrum of Strong Ground Motions

Cheng Wei Liu Guangdong Yi Weijian (Dept of Applied Mathematics,Hunan Univ,410082,Changsha,P R China)  
By introducing the concept of main value of phase difference spectrum,the relationship between probabilistic distribution functions of phase spectrum or phase difference spectrum and their main values are discussed.The incompatibility of probabilistic properties of phase spectrum and phase difference spectrum can be overcome effectively by distinguishing phase spectrum and phase difference spectrum from their main values.The distribution functions of main values of phase and phase difference are calculated and modelled on the assumption that the probability distributions of phase difference spectrums are normal,the results is very similar to Ohsaki's statistical results from real strong ground motion records .It means that the approach of this paper is reasonable.
