Calculation of punching shear strength of steel fiber reinforced concrete flat slabs

Abstract

The paper deals with analysis of calculation of punching shear strength of reinforced concrete flat slabs with or without steel fibers in punching shear zone. The analysis shows, that the type, shape and strength of steel fibers has an influence on punching shear strength. The empirical method, evaluating these factors and calculating the punching shear strength according to Lithuanian and Euro Codes, is presented and discussed.
