Comparative analysis of punching shear strength for reinforced concrete slabs based on database

Although various studies and hundreds of laboratory experiments related to the punching shear strength of reinforced concrete (RC) slabs have been published and conducted respectively, code provisions have been developed based on a rather limited subset of the available test results and those studies ignored the details of test slabs and experiments. A database of 678 specimens has been categorized and structured depending on the test set-up type through the present study. In this study, eight equations for the punching shear strength prescribed in specifications were evaluated based on the database. A simplified strength equation is also proposed from the database.
