摘要

中性层与横截面的交线称为中性轴,梁结构在弯曲受损时中性轴的位置会发生变化。制作矩形横截面再生混凝土梁试验模型,并进行了静力纯弯曲加载试验,用来验证基于中性轴位置变化的损伤识别方法。根据对试验结果的数据分析,通过中性轴的位置变化能够判断出结构是否发生损伤。

Abstract

The intersection of neutral layer and the transverse section is called neutral axis. The position of neutral-axis will be changed when the corresponding beam structure is damaged. In this work, the static loading test of recycled concrete beam is carried out to verify the damage detection method based on neutral axis position. Experimental results show that structural damage can be detected by the change of the neutral-axis position.
