| Abstract: | The construction quality defects of a high building are presented and the reason is further analyzed. The segment of the building which have been c onstructed and have not been constructed are calculated according to different c oncrete strength. The calculation really reflects the change of structure bearin g capacity of resistance to the side force and axial compression ratio of wall and column. The strengthening methods in relation to the frame beam, column and shear wall are discussed. A treatment method strengthening to the quality de fects are introduced as reference for strengthening the quality defects of the s ame kind of engineering. |

| Keywords: | strengthening axial compression ratio carbon fib er fabric post-embedding reinforcement |
