| Abstract: | North Bund Magnolia Plaza Hotel tower is a over-limit high-rise building with the total height of 171 meters,frame-core-outriggers structural system with strengthened storey is used in this structure. Elasto-plastic dynamic analysis under rare earthquake action is conducted on the platform of PERFORM-3D software. The whole structure's performance is evaluated in the article,and some typical components' damage index is focused on,including the core wall,steel frame,steel reinforced column,belt truss and link beam. The method and results can offer some reference to the project's design and is also useful to other similar structural design. |
