摘要
文章结合一端张拉(另一端先锚固)施工工艺对预应力碳纤维布张拉及放张时应力分布、预应力传递长度以及碳纤维布在预应力长期作用下的回缩量等作了测试。通过测试结果可基本掌握施加预应力后碳纤维布的应力分布情况,并可为以后的相关研究提供借鉴、参考。
In this article, it describes that the beams strengthened with CFRP sheet which prestressed at one end (the other end anchored previously) , the stress distribution and prestress transferable length of CFRP sheet are tested when CFRP sheet is prestressing and releasing, shrinkage of CFRP is also tested . All the work gives some supports to this research.
