[Help] 1992 The brick-concrete wall of the old house was cracked laterally.

The cracking of your wall can't be judged only by your description, which is the inevitable factor of your wall cracking, because the wall was knocked off on the fifth floor. What is the specific reason? According to the structural diagram of the building and the specific situation of the site. But I can still give some suggestions for your reference:

1, is the wall between the small square hall and the bedroom a load-bearing wall? If it is a load-bearing wall, no one can tear it down without authorization. Demolition will affect the structural safety and public safety. You got it?

2. If it is a load-bearing wall, have you removed the legal reinforcement design documents of the relevant qualification units? If not, it can be classified as unauthorized demolition.

3. If the load-bearing structure is dismantled without authorization, the illegal act shall be stopped immediately, and if losses are caused to the relevant personnel, compensation shall be made. If the circumstances are serious, criminal responsibility shall be investigated.
