摘要：

In order to increase the strength and deformation capacity of flat slabs, punching shear reinforcement is used as an effective solution. Several types of punching shear reinforcing systems have been developed in the past. This work aims to analyze the behavior of unbonded post-tensioned slab subjected to punching load provided with Inverted-U Shaped Reinforcement. By using a finite element software, the results were compared with that obtained from an experimental investigation previously done. The experimental results were also compared according to ACI provisions for punching shear strength. Good correlation was done between what was tested and the numerical results.
