摘要

为研究地震作用下钢筋锈蚀对试件性能退化影响的规律

对6个锈蚀钢筋混凝土受弯构件进行低周反复荷载试验

得到不同锈蚀程度试件的滞回曲线及骨架曲线

分析了钢筋锈蚀对试件强度和刚度的影响。试验发现

随着钢筋锈蚀程度的增大

各试件强度退化基本呈增大趋势;低锈蚀率试件由于锈胀内力的存在

强度退化相对比未锈蚀试件和高锈蚀试件大;随着锈蚀率的增大

试件加载和卸载刚度总体上逐渐减小

且随着位移的增大而持续减小。此外

还分析了锈蚀钢筋混凝土结构刚度退化机理。成果可供锈蚀钢筋混凝土结构抗震性能研究参考。

Abstract

For the purpose of understanding the mechanical property degradation law of corroded reinforced concrete structures under earthquake

this paper carries out the low cyclic loading test on six corroded flexural members

obtains the hysteresis loop and skeleton curve of reinforced concrete specimens with different corrosion degrees and analyzes the effects of reinforcement corrosion on specimen strength and stiffness.It is revealed that the degradation of specimen strength is increased as corrosion rate of reinforcement increases;the strength degradation of low rust specimens is higher than that of non-corrosion specimens and seriously corrosion specimens due to existance of the corrosive nternal force.Besides

the leading and unloeding stiffness of specimen generally decreases and keeps decreasing tendency with the increasing of displacement.Moreover

the stiffness degradation mechanism of corroded reinforced concrete structure was analyzed.The results of this paper provide some references to the seismic performance study of corroded reinforced concrete structure.
