摘要

焊接型I形钢是工程上普遍使用的钢材，在循环荷载下在翼缘与腹板的连接处容易发生疲劳破坏。由于破坏的突发性和损失的惨重性，需要及时检测到损伤的发生。本文在探究钢梁内应力波传播机理的基础上，利用小锤敲击钢梁表面产生宽频冲击波，通过粘贴在I形钢梁表面的光纤干涉仪接收应力波信号，通过对信号频谱分析，判断损伤的存在以及位置。数值分析和实验研究结果表明，采用冲击-光纤法检测焊接型I形钢梁翼缘与腹板连接处疲劳损伤具有可行性。

Abstract

Welded I-section steel members are widely used in engineering, and it is prone to fatigue damage at the web/flange junction under cyclic load.Due to the sudden damage and the heavy losses, it is necessary to detect the damage in time.Based on the study of stress wave propagation mechanism in steel beam, a broadband impact wave was generated by a hammer striking on the surface of a steel Ⅰ-beam, and the fiber interferometer was attached to the surface of steel beam to receive the stress wave signal.By analyzing the impact echo signal spectrum, the existence and location of the damage was determined.Numerical analysis and experimental results show that it is feasible to detect the fatigue damage at the flange/web junction of the steel Ⅰ-beam by the impact-optic method.
