A model for the prediction of the punching resistance of steel fibre reinforced concrete slabs centrically loaded
With the aim of contributing for the development of design guidelines capable of predicting with high
accuracy the punching resistance of steel fibre reinforced concrete (SFRC) flat slabs, a proposal is presented
in the present paper and its predictive performance is assessed by using a database that collects the
experimental results from 154 punching tests. The theoretical fundaments of this proposal are based on the
critical shear crack theory proposed by Muttoni and his co-authors. The proposal is capable of predicting the
load versus rotation of the slab, and attends to the punching failure criterion of the slab. The proposal takes
into account the recommendations of the most recent CEB-FIP Model Code for modelling the post-cracking
behaviour of SFRC. By simulating the tests composing the collected database, the good predictive
performance of the developed proposal is demonstrated.Fundação para a Ciência e a Tecnologia (FCT
