摘要
文中研究了一种基于压电传感的钢管混凝土结构界面缺陷监测试验,将压电材料制成埋入式压电传感器,并在此基础上,设计了一套监测系统,利用波动分析法对钢管混凝土的界面缺陷进行监测和分析.文中设计了不同尺寸的界面剥离缺陷和无缺陷监测组,从基于幅值和声时的时域和频域角度对应力波测量结果进行对比分析.结果表明,本研究所提出监测方法能够识别一定范围内的钢管混凝土界面缺陷.
Abstract
The paper presents a monitoring test for detecting interfacial defects in concrete-filled steel tube(CFST)structures using piezoelec-tric sensing.The embedded piezoelectric sensor is utilized to measure and analyze the interfacial defects of CFST structures through the imple-mentation of a monitoring system and wave analysis principles.A monitoring group consisting of various sizes of interface peel defects and de-fect-free samples is designed.The stress wave measurement results are compared and analyzed in both time-domain and frequency-domain perspectives based on amplitude and sound time.The findings demonstrate that the proposed monitoring method can effectively identify interface defects within a specific range.
