Punching shear of RC flat slabs – Review of analytical models for new and strengthening of existing slabs

The conversion of existing buildings, development of standards, material deterioration and detailing deficiencies have led to a need for strengthening an increasing number of concrete flat slabs against brittle punching shear failure. However, existing analytical and design models do not yet take into account the specific aspects of strengthening slabs against punching shear. More than 40 models exist for predicting the punching shear strength...
