Abstract:The design thought, structure layout, load transfer path, structural design characteristics and key nodes design of a tree-shaped building were introduced. PMSAP and ETABS software were used for pedestrian comfort analysis and performance design of the cantilever structure. The structural performance of the tree-shaped building and the different mechanical results of the structure under different construction sequences were discussed, and the corresponding foundation design was introduced. The results show that the tree-shaped building can realize the seismic ductility target, and can provide enough seismic bearing capacity, so that the structure is safe.

Keywords:bundle corewall; torsion effect; floor stress; construction sequence; seismic performance
