The Wuguan Building at the former site of the British Embassy is a national cultural relics protection unit. The rigid connection scheme was adopted in the first translation design in 2004, then it was parked in the middle site for nearly 10 years, and the connection work was started in 2013. Considering the high protection level and strict protection requirements of the Wuguan Building, the isolation connection scheme can reduce the reinforcement workload of the superstructure. Moreover, the efficiency and reliability of the isolation technology in response to earthquakes response have been verified by a large number of engineering examples, so the calculation and analysis of the isolation connection scheme are carried out. At the same time, in order to meet the structural requirements of the installation and maintenance of the isolation bearing, the existing underpinning beam, the down-slide beam, and the foundation raft are required to be strengthened and transformed. The calculation results show that the design of the isolation structure meets the requirements of seismic performance design objectives, the maximum deformation of the isolation layer under the 8 degree rare earthquake meets the requirements of the code, and the torsional effect of the upper structure can be significantly reduced after the isolation layer is installed.
