碳纤维加固钢混结构的特性研究

The Research on the Properties of Concrete Structures Fortified by Carbonized Fibre

对原有混凝土结构进行加固补强、翻新改造,最大程度利用现有建筑资源,保证其使用安全、延长使用寿命,是当今国际工程界关注的重大课题之一,也是建筑业可持续发展的必然趋势。通过与加大截面加固法、外包钢加固法、预应力加固法及改变结构传力途径加固法进行比较,提出碳纤维加固补强混凝土结构所用的碳纤维和粘结材料的性能、施工方法及保证质量的技术关键。

It is one of most concerned problems in international engineering circle, strengthening existing concrete structures, reconstructing them, making the best use of the existing building resources, and guaranteeing the safety of their exploitation, extending their durability, also it is the tend of continual development of building industry. Comparing with the strengthening methods such as enlarging cross section, wrapping steel, prestressing, and changing the way of transmitting forces of the structures, the ...
