CFS加固不同的梁、柱节点,可以提高其强度、延性、耗能能力等抗震性能,并且对震后损坏的试件,采取例如:更换受弯钢筋和采用适当的CFS方案、CFS包层 + 粘性钢胶、CFS外部约束等可以恢复其抗震性能。在一定CFS包裹范围内,随着CFS包覆层数的增加,混凝土抗压强度得到提高,其中一层包覆与未加固试件相比,抗压强度增幅最大。CFS对抗压强度提升上:50要优于30 mm、完全优于局部约束、水平优于螺旋条、全包优于条包方案。CFS环向加固可以提高抗弯能力,并且提高抗弯强度的效率随着与所用混凝土抗压强度呈反比例关系,在对梁抗弯强度提升方面:半u型包箍加固优于叠层、2 m CFS条优于1 m CFS条、全方案优于底部方案和半方案。目前研究人员,主要研究CFS包覆面积、位置、以及不同的加固体系在高温下加固建筑物耐火性能。
