Abstract: Existing old industrial factory buildings were inspected and assessed, and their drawings were restored.The results showed that the requirements for the bearing capacity of many structural components cannot been met, which indicated the structure could not continue to be used.Moreover, the structural form of the factory building had already been outdated.Based on the inspection and assessment results, the appropriate reinforcement scheme was selected to renovate and reinforce the structure, transforming its structural type into the frame-shear wall structure that accorded with the related codes, and the bearing capacity of each structural component could meet the requirements of the codes, so that it could been put into use again and improve production efficiency.
