Evaluation of punching shear strength of reinforced Concrete slabs based on database

Abstract

Although various studies related to the punching shear strength of slabs have been published, databases related to punching shear strength are small in size. A database of 313 specimens has been structured through the present study, compared to the 114-data compiled by Kakuta et al. (1974) and the 138 data compiled by Gardner et al. (1996). In this study, six equations for the punching shear strength prescribed in specifications were evaluated based on the database. This paper includes a discussion of the parameters of punching shear strength in JSCE and AIJ specifications. A simplified strength equation is also proposed from the database.
