摘要
为研究外贴CFRP板粘贴长度对混凝土结构粘结性能的影响,设计5个不同CFRP板粘结长度的混凝土试件并进行三点弯曲加载试验,采用数字散斑分析技术研究试件应变演化。结果表明,随着CFRP板粘贴长度的增加,混凝土结构三点弯曲承载力增加。
In order to study the influence of the adhesion length of CFRP plate on the bonding performance of concrete structure,five concrete specimens with different CFRP plate bonding length were designed and subjected to three-point bending loading test.The digital speckle analysis technique was used to study the strain evolution of the specimens.The results show that with the increase of the length of the CFRP plate,the three-point bending capacity of the concrete structure increases.
