Some questions on three kinds of transfer storey such as beam, box-shaped beam and thick slabs, are discussed. The design concept and key of beams of supported-frame and the height of transfer storey are also discussed. The designers should carefully design the transfer structure in seismlc area according to the seismic intensity. Finally, the thick slab transfer storey of a multi-tower structure with enlarged base in Chongqing is introduced.
