heal.abstract	A new approach to designing reinforcement to resist punching shear is discussed. The loss of bond may occur within the two slab strips, which are considered to contain the flexural reinforcement. The reduction of the compressive zone depth increases the intensity of the compressive stress field leading to dilation of the volume of concrete, which causes the development of transverse tensile stresses in the adjacent regions. The verification of the proposed method is based on the comparative study of the results obtained from numerical tests on slabs designed in accordance with both the proposed method and the methods adopted by current codes such as the ACI 318 and the EC 2. Designing the shear reinforcement in accordance with the code adopted methods leads to analytical predictions of the load-carrying capacity which are considerably smaller than the design value. It is found that the effect of increasing the code specified amount of shear reinforcement to the amount specified by the proposed method is ineffective.	en
