Abstract: The structural design on the new ward building of Henan Provincial People's Hospital is mainly to deal with an out-of-code high-rise building, the seismic evaluation of the existing building, the design of the elevator hall, the design of the elevated corridors between the existing building and the new building etc. Comparative analysis with multiple softwares and conceptual reinforcements were carried out to achieve seismic performance objectives. The sliding bearing was adopted as a weak link for the elevated corridors, the comfort checking and the vertical seismic analysis were done to guarantee the bearing capacity and the usage safety. In addition, the pre-set slide limit of the bearing was used under the wind load and the normal service condition, which could be a reference for similar projects.

Keywords: out-of-code high-rise building; seismic performance objective; elevated corridor; sliding bearing; vertical earthquake; comfort checking
