摘要
结合某工程实例,对旧楼改造方案的确定和在改造加固中碳纤维对框架柱的加固进行了论述。通过加固前后框架柱轴压比的变化,表明对不满足抗震延性要求的框架柱,碳纤维加固能有效地提高框架柱的延性。
Based on some actual engineering projects,the old building reconstruction scheme and strengthen frame column by CFRP are presented.Passing the variance in axle compression ratio of column which are reinforced before and after,it makes clear that CFRP is very vailability in strengthening if the frame columns could not meet the needs of ductility of earthquake-proof.
