摘要

为了研究光圆钢筋与混凝土的黏结滑移性能，针对不同黏结长度的钢筋混凝土试件进行了数值试验，得到光圆钢筋从混凝土基体中拔出损伤破坏的全过程曲线，以及对应的声发射结果。同时进行了单筋的中心拔出物理实验并对实验中的声发射现象进行监测，实验结果较好地证明了数值试验结果的有效性，并对数值试验分析的参数调整提供了参考。物理实验和数值试验结果分析均表明：随着黏结长度的增加，单筋拔出力越来越大。

Abstract

A numerical code RFPA

has been adopted to conduct numerical analysis on the impact of bond length on the plain bar. With the numerical mode

the entire damage process of the plain bar as being pulled out from concrete block and the corresponding AE result have been analyzed. To verify the numerical simulation results

a pullout test has also been carried out and corresponding acoustics emissions have been collected. The physical test has similar results compared with the numerical analysis. Both tests indicate that the peak pullout force also increased with increased bond length.
