摘要
本文以一个加固改造工程为例,介绍了应用碳纤维复合材料(CFRP)对钢筋混凝土梁进行加固的计算方法及施工工艺,着重对复核原RC梁截面承载力,判断是否需要加固以及采用不同规范、规程计算同一加固梁的正截面承载力进行了较全面的论述。通过该项改造工程的设计及施工实践,证明了CFRP加固技术的适用性,对类似工程具有一定的参考价值。
Through a strengthening and reconstruction project, this article introduces the calculation method and construction technique for RC beams strengthening with CFRP. It focuses on calculating the bearing capacity of normal ＆ inclined sections on pre-strengthened RC beams to verify whether reinforcement is required, as well as the calculation on the bearing capacity of normal sections on strengthened RC beams with various technical standards and specifications. The design and construction practice in this project proved that the CFRP strengthening technology was applicable, which should be a valuable reference for similar projects.
