A reinforcing method is introduced, concerning the inclined and cantilever features in the structure of the Palms together dagoda in the Famen Monastery and the cracking in the floor slab of 54 meters high. According to the actual situation, the welding of the strengthened metal and the structure on the nodes is difficult to achieve. In order to make some improvement, we use bolt connection run throng the wall body instead of steel belt and steel bone welding, which will make the transmission of the structure more clear, shorten the construction period and ensure the engineering quality effectively. This method can also be used for the reinforcement in concrete structures of large span and tall buildings. Therefore, the discussion of processing technology dealing with the combination of the structural cracks in floor which this article focuses on, has some reference value on similar projects.
