The following reinforcements were done: Adding ferrocement mortar to the wall surface, pouring concrete lamination layer on the precast floor, and connecting new structure with the existing structure.These reinforcement schemes could meet the anti-seismic requirements of current code, mprove the bearing capacity of the structure.The results showed the rationality of the reinforcement schemes
