Precast eurocode 25/24/2023 ![]() Besides the performed tests results, the analysis of the other investigations of the footing punching rested on the real soil is also included. In order to quantify the level of safety in Eurocode 2 and in fib MC 2010, their design results are compared with the test results of the series of footings tested in completely realistic boundary conditions in terms of the subgrade soil. The reason for this is because standards define differently the position of the critical perimeter in which the punching shear resistance should be determined, and quantify the influences of the main parameters like effective depth, shear slenderness, compressive strength of concrete, longitudinal reinforcement ratio and tension yield stress of reinforcement in different ways. Punching shear resistance of column footings and foundation slabs varies significantly in different standards.
