Structure Design of Prestressed Concrete Hollowplate Floor with Large Span in Framecore Wall System /Shen Keli (Tsinghuayuan Architectural Design Ltd., Shenzhen 518052, China)
Abstract:A design example of adopting prestressed concrete hollowplate floor with large span in framecore wall system is introduced, and the design method and experience are summarized. The comparison with the common beamslab system for the same project is presented. The practice shows that the technique can be used in the highrise framecore wall structures and the hollowplate floor can be calculated with the method  of equivalent beam.
Keywords:prestressed concrete hollowplate; transmit force in twoway; rigidity ratio； bending resistance
