摘　　要：本文系统地提出了无粘结预应力混凝土板的冲切设计及计算方法。在冲切强度计算中,计入了无粘结预应力筋所产生预压应力的有利影响。介绍了采用剪力块和配筋的剪力增强措施、计算方法和使用限制条件,以及冲切设计构造措施。The paper presents design and analysis methods for punching of unbouded post-tensioned concrete slabs. In the punching strength computation the advantageous effect of average prestress is taken account. Shear reinforcements of shearheads made out of steel channels, or Ⅰ beams, bent bars and beam stirrups for two-way slabs are introduced, and their computation methods, limiting conditions in use, as well as some construction details are provided.
