heal.abstract	The phenomenon of the punching failure of circular reinforced concrete slabs, and the effect of the vertical prestressing on the failure mechanism has been investigated in this paper. The phenomenon was investigated using a finite element package and results were compared with existing experimental data. Results show that slab's ultimate behavior is governed by material behavior within the compressive force path. Vertical prestressing improves triaxial compressive stress state of the critical zone within the compressive force path, and thus results in significantly increased ultimate load and ductility of the slab. © 1993.	en
