Abstract:The office building in Korea IT Industrial Park is an out-of-code high-rise structure with complex connection between two towers, and the building adopts frame-shear wall structural system. The design  and analysis  for this building were introduced. Firstly, the seismic performance objectives of the building were proposed based on the out-of-code details of the structure. Then, the seismic behavior of this building under frequent earthquake was studied. Special attention was paid to the connection part between the two towers, and several parameters were analyzed, including the multiple seismic fortification line analysis, tensile analysis of the shear walls, as well as the seismic capacity, the comfort and the connection joint stress of the floor of the connecting body. At the same time, the performance of the structure under rare earthquake was verified by static and dynamic elastic-plastic analysis. Finally, the seismic strengthening measures of the structure were put forward.

Keywords:out-of-code high-rise structure; complex connection; structural analysis; seismic strengthening measure； connected structure
