摘要
以嘉兴某桥梁不同截面动应变为对象,构造不同测点的互相关函数,进行结构损伤分析。提出了基于回归分析的动应变温度效应剔除方法,并对剔除温度影响前后的动应变相关函数幅值进行对比,结果表明剔除温度效应有利于准确判别结构损伤状况。
The analysis of structural damage detection based on correlation function of different stations was studied with dynamic strain responses of different cross of a bridge in JiaXing, A method of eliminating the effect of temperature was proposed, then compared the correlation function amplitude, the result showed that eliminating the temperature effect was helpful for accurately jud- ging the damage of structure.
