碳纤维布加固提高钢筋混凝土柱轴压比及延性的工程应用

The application of CFS for increasing the axial compression ratio and ductility of column

论述了利用碳纤维布材料来加固提高钢筋混凝土柱轴压比及延性的设计依据、方法和施工经验,特别是解决新老抗震规范的更迭所带来的柱加密区配箍率不够的普遍性问题,可供同类工程结构的抗震加固作参考。

This paper discusses the design basis, methods and construction experiences for RC columns wrapped with carbon fiber sheet (CFS) for increasing their axial compression ratio and ductility, especially solve the universal problems for short of hoop rate in column dense area caused by the change of new and old seismic design specifications, and can give a reference to seismic strengthening for similar structure application.
