碳纤维布加固混凝土构件的粘贴构造与锚固技术

经试验研究,用碳纤维布加固混凝土构件可以有效提高构件的极限承载力和改善构件的变形性能,在极限荷载作用下已加固构件的破坏模式常为粘结锚固失效。因此,采用合理的粘贴构造和锚固措施是实现有效加固的关键环节。本文阐述这种加固方法中的构造要点,包括基面、粘贴、塔接、锚固及防护等。

Sticking Constitution and Anchorage of Carbon Fiber Sheet in Reinforcement Concrete Structures

As a result of test research, the ultimate strength and the deformation behavior can be raised greatly on reinforced concrete members by using carbon fiber sheet (CFS). The failure mode of the strengthened members is of debonding failure under the action of ultimate load. Therefore, the rational sticking constitution and the anchorage measure are the key links to realize effective reinforcement. This paper elaborates main points of constitution by CFS, including basic surface, sticking, lapping, anchorage and protecting etc. [
