Abstract

Abstract: Carbon Fiber Reinforced Plastics (CFRP), a new kind of engineering material is widely used in civil engineering to strengthen old structures. The article studies the performances of short concrete column limited with CFRP under axial load in lab and compares them with that of short common concrete column and concrete column with spiral reinforcement. Experiments show that under axial load the short concrete column limited with CFRP has an amazingly higher lording capacity. The article is helpful

Key words: CFRP, limited concrete, short column, axial load

摘要： 碳纤维增强塑料(CarbonFiberReinforcedPlastics),简称CFRP,是一种新型的工程建筑材料,目前在土建工程中运用十分广泛.笔者对CFRP约束砼短柱在轴心受压状态下的力学性能进行了试验研究,并和普通砼短柱、普通螺旋箍筋短柱的力学性能进行了对比,对比试验表明:CFRP约束砼柱在轴心受压情况下,可以大大提高构件的承载能力.在工程中采用约束砼柱这一结构新形式和利用CFRP加固旧砼柱具有一定的参考价值

关键词: 碳纤维增强塑料(CFRP), 约束砼, 短柱, 轴心受压
