摘要:
为研究疲劳荷载下玄武岩纤维增强聚合物(BFRP)-混凝土界面粘结的失效规律及损伤模型,本文针对5个试验对照组中的15个BFRP加固混凝土试件进行了双剪试验,分析了这些试件的界面破坏模式、界面受剪承载力、加载端荷载滑移曲线和界面黏结滑移关系等力学性能指标,并研究了疲劳荷载下BFRP-混凝土界面的黏结性能和损伤演化过程.分析了试验的局部粘结应力随疲劳作用的退化规律,同时基于试验数据得出了界面破坏随荷载值的变化规律,并建立了简单的损伤三阶段模型.
Abstract:
In order to study the failure law and the damage model of the basalt fiber reinforced polymer(BFRP)-concrete interface bond under fatigue load,the double-shear tests were conducted on the 15 BFRP reinforced concrete specimens in the 5 experimental control groups and the mechanical property indexes of these specimens such as the interface failure mode,the interface shear bearing capacity,the load slip curve at loading end and the interfacial bonding slip relationship were analyzed,and the bonding properties and the damage evolution process of the BFRP-concrete interface under fatigue load were studied.The degradation law of the experimental local bond stress with fatigue action was analyzed,at the same time,the variation law of the interface failure with load value was obtained based on the test data,and the simple three-stage damage model was established.
