Advances in ground motion attenuation relationship of Chinese mainland

Ground motion attenuation relationship is one of the primary methods for site ground motion estimation. In this paper, firstly, the development of the ground motion attenuation relationship equations is briefly described. Then it analyzes the importance of the conversion method proposed by Mr. Hu Yuxian, reviews the development process of the attenuation relationship in the Chinese mainland, and focuses on research progress of horizontal ground motion, vertical ground motion, and other ground motion parameters. Finally, the limitations existing in the study of attenuation relationships are discussed, and suggestions for developing the strong ground motion database and the attenuation relationship in regions with poor ground motion records are put forward.
