Abstract

The invention relates to a clustering method and device for seismic oscillation data grouping. A clustering basis is obtained by analyzing the spectral characteristics and influence factors of seismicoscillation, then clustering is carried out in a K-means clustering mode, and the clustering basis is the initial frequency and the termination frequency of frequency bands in an energy set, or the magnitude and the propagation distance. Compared with the prior art, the characteristics of the seismic oscillation data are utilized for clustering and data grouping, and the use efficiency and convenience of the database are improved.

Description

technical field [0001] The invention relates to the field of seismic structure optimization, in particular to a clustering method and device for grouping seismic data. Background technique [0002] Under different seismic environments, the spectral characteristics of ground motion data are significantly different. In engineering practice, the ground motion data are often grouped according to the differences in the spectral characteristics, and the ground motion data of different groups are selected for the seismic analysis of the structures in different seismic environments, so as to ensure that the structure has sufficient strength when a real earthquake occurs. safety stock. [0003] Since the ground motion data under different site types show obvious differences in spectral characteristics, the seismic codes of various countries generally group them according to site conditions. However, even under the same site category, the spectral characteristics of ground motion da...
