Abstract

Results of the latest experiments have revealed that the maximum punching resistance defined from crushing of concrete struts at the perimeter of a column in EC2 is an insufficient criterion for limitation of maximum shear forces at the vicinity of columns. Therefore further limitation has been introduced in STN EN 1992-1-1/NA. The paper will deal with the new requirements concerning of maximum punching shear resistance which is based on the kmax factor and punching shear resistance without shear reinforcement vRd,c.
