【提要】介绍了两榀两层两跨钢筋混凝土框架模型在低周反复水平加载下的试验过程和试验结果，其中一榀作为对比试件，另一榀在梁柱端部用碳纤维布进行了加固。试验结果表明，梁柱端部加固后，框架的水平承载能力、位移延性和耗能能力都得到了提高。适当选择加固长度，可以实现塑性铰和破坏位置的转移。

Abstract:The experimental schemes and results of two RC frame models with two s
pans and two levels under static cycle horizontal loads are reported. One of the
 frame models serves as the control specimen,and the other is strengthened
in the end sections of the beams and columns with CFRPs. The experimental result
s show that the horizontal load capacity,the displacement ductility and the cap
acity of energy dissipation of the strengthened specimen are improved. An approp
riate strengthened length can shift the plastic incursions and failure sections.
