碳纤维约束钢筋混凝土短柱轴心受压性能研究

Research on Carbon Fiber Reinforced Concrete Short Columns under Axial Compression Properties

碳纤维增强塑料(Carbon Fiber Reinforced Plastics),简称CFRP,是一种新型的工程建筑材料。本文对CFRP约束钢筋混凝土短柱在轴心受压状态下的力学性能进行了试验研究,并和普通螺旋箍筋短柱的力学性能进行了对比,结果表明:CFRP约束混凝土柱在轴心受压情况下,可以大大提高构件的承载能力。

Carbon Fiber Reinforced P1astics（CFRP）,a new kind of engineering mateha1,is widely used in civil engineering to strengthen old structures.The article studies the performances of short concrete column confined with CFRP under axia1 1oad in1ab and compares them with that of short concrete column and concrete column with spira1 reinforcement.Experiments show that under axia1 1oad,the short concrete column confined with CFRP has an amazing1y higher bearing capacity.
