Influence of Local Deformations of Transfer Structures on Seismic Design
The introduction of transfer structures between the high zone and the low zone of a high-rise building has become popular and sometimes even inevitable in modern building developments. Under earthquake actions, concentrated stresses and large lateral displacement may occur at those locations where stiffness changed significantly either on plan or in elevation. In this study, based on the results of the previous shaking table test and numerical analyses, general seismic behavior of transfer structures is identified. The mechanisms for the formation of soft story below the transfer floors, the abrupt change in inter-story drift in the vicinity of transfer story and shear concentration due to local deformation of transfer structures are summarized. This study can improve the general understanding of the seismic response of concrete buildings with transfer structures in lowto- moderate seismicity regions.
