SEISMIC BEHAVIOR OF THE BOX-TYPE TRANSFER STOREY WITH THE TOP SHORT-LEG SHEAR WALLS IN HIGH-RISE BUILDINGS

摘要

Wuhan Fruit-lake Building was initially designed as a frame-tube structure with a girder transfer storey. Later, the structure of the main tower was changed to short-leg shear wall structure with box-type transfer storey. Finite element analysis software is used to establish a finite element model of the whole building. Based on model analysis and seismic response spectrum analysis, the vibration characters of the model are revealed and analyzed. It also can be found that the existence of the box transfer storey results in a sudden change of seismic response of the whole building. Therefore, a partial solid FE model of the box transfer storey with the short-leg shear walls is built and calculated. The stress distribution and transfer within the transfer storey structure are clarified. According to above FEA results, some beneficial advices are also put forward for the design of this key structural part in high- rise building.
