摘要
通过模型试验,对钢桁架桥梁进行了裂纹识别的研究。在裂纹位置固定的情况下,以不同程度裂纹深度为工况进行了试验,测试信号经过时域分析、傅立叶谱分析和传递函数分析,得到了桥梁损伤识别的一些有益的结论。
Experimental study for damage detection of a steel truss model is the central part in this paper. Crocking depth is different and the location is changeless. It is classified according to four eases. The process involves the observation of featured parameter that can reliably provide the states of the damaged degree, the method to efficiently assess the health state. It comes to some efficient conclusions through the time- history method, FFT spectrum analysis and the analysis of transfer function.
