This project is a reconstruction and reinforcement project of the shopping mall. The first floor top of the original structure is partially reconstructed, and a part of the floor is added (the same as the second floor top of the original design structure), with local openings. After adding floor slabs, some beams need to be strengthened due to the increase of load; The newly opened part is located at the beam edge, so there is no need to strengthen the plate edge, and some beams around are strengthened; Exposed reinforcement after opening must be protected.
Including: design description, floor (current) structural plan, floor (after reconstruction) structural plan, and new floor beam reinforcement plan, three drawings in total.
