Data-Driven Models for Predicting the Shear Strength of

In this paper, novel data-driven models are presented for predicting the maximum shear strength of rectangular and circular RC columns. To this end, two extensive experimental databases for both types of columns were used in the present study. The data were randomly partitioned into calibration and validation sets.

PDF Punching Shear Strength of Reinforced Concrete Slabs

As shown in Fig. 1, the punching shear strength decreases with increasing rotation of the slab. This has been explained by Muttoni and Schwartz12 as follows: the shear strength is reduced by the presence of a critical shear crack that propagates through the slab into the incl ined compression strut carrying the shear force to the column (Fig. 2
