【摘要】 本文通过42个试件的轴压试验,测得混凝土棱柱体试件的应力、应变数据,并且得到不同轴压比的情况下,CFRP约束预压混凝土棱柱体试件的应力—应变曲线,并对其进行分析;与此同时还得到未约束混凝土试件、CFRP约束混凝土试件两类对比试件的应力—应变曲线,并将后者与前者进行对比分析,为实际工程加固提供试验依据。
【Abstract】 42 samples of axial compression were tested in this paper,and data of stress and strain were obtained. From the data,stress-strain curves of CFRP restrained preloaded concrete prism specimen with different axial compression ratio were got and analyzed.At the same time,curves of nonrestrained and CFRP restrained specimen were also obtained.Through comparing these curves with the former,experimental evidence can be provided for the reinforcement of actual engineering.
【Key words】 CFRP； prismy sample； preloaded concrete； axial compression ratio； stress-strain relationship；
