Abstract

Acoustic emission data of the whole Acoustic emission data of the whole failure process of prestressed reinforced concrete beams by the test of hierarchical loading are collected then introduce a detailed description of using the least squares method to calculate the b-value using Seismology b-value theory as the basis and study the change of the b-value.The results show:theoretical analysis of acoustic emission data is feasible by using the b-value of seismology,at the same time, there is a certain relationship between the process of the b-value change and the failure process of the specimen.
