After the completion of the basement,the upper apartment type had to be changed,the original basement column wall is re-tained,and the upper structure is converted by thick slab in the basement roof.This paper introduces the performance-based design a-dopted by thick slab conversion and how to analyze the stress of the floor around the main building under the condition that the built base-ment is closed with the pouring belt.The analysis results show that:The final thick plate conversion has been strengthened after perform-ance-based design,corresponding measures have been taken to the thick plate conversion site and the root of the planting reinforcement,and the reinforcement of the connecting part of the main building and the pure basement has been strengthened according to stress analysis,effectively ensuring the safety of the structure.
