Spreadsheet validation for Flat slabs in eccentric punching shear experimental database and analysis

Eccentric punching shear can occur in concrete slab-column connections when the connection is subjected to shear and unbalanced moments. Typically, this situation results in edge and corner columns and is thus a common practical case. However, most punching experiments in the literature are concentric punching shear experiments. This paper presents a database of eighty-eight experiments on flat slabs under eccentric punching shear, including a summary of the testing procedure of each reference and a description of the slab specimens. Additionally, a linear finite element analysis of all the specimens is included to determine the relevant sectional shear forces and moments. Finally, the ultimate shear stresses from the database experiments are compared to the shear capacities determined with the ACI 318-19, Eurocode 2 NEN-EN 1992-1-1:2005, and the Model Code 2010. The result of this comparison shows that the Model Code 2010 is the most precise model with an average tested over the predicted shear ratio of 0.96 and a coefficient of variation of 27.96%. It can be concluded that this study represents the inconsistencies of the currently used methods and the lack of experimental information.
