Abstract: Glass Fiber Reinforced Plastics(GFRP), 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 GFRP 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 to use the concrete column limited with CFRP and strengthen old column with CFRP.

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

摘要： 传统的砼受压构件中采用配置箍筋的方法来达到对砼约束的目的.本文对玻璃纤维增强塑料(Glass Fiber Re-inforced Plastics,简称GFRP)约束砼圆柱的力学性能进行了分析和试验研究,并与普通砼圆柱进行了对比.
