摘要：
In order to study the seismic Performance of new fully modular prefabricated assembled bridge piers and the application of acoustic emission monitoring teehnology in the condition monitoring of bridge piers, In this paper a set of new assembled bridge pier speeimens was designed, a low-week reeiprocating loading test was carried out, and the acoustic emission teehnology was adopted to monitor the damage development of the piers in real time in the process of the test. The correlation study of force and displacement curves and the quantified acoustic emission signal characteristics was carried out to describe the damage destruetion process of the speeimen in multiple aspects. The test results show that the damage evolution process of the new bridge pier strueture under reeiprocating load can be divided into crack development stage, strengthening stage, energy consumption stage and rapid destruetion stage aecording to the change and aecumulation of acoustic emission energy. Through the comparison of mechanical data and acoustic emission activities, the effectiveness and aecuraey of acoustic emission teehnology were proved in the State analysis and assessment of the damage evolution process of the strueture, which can provide a reliable basis for engineering practice. © 2025 Chinese Vibration Engineering Society.
