Shear strengthSlabsStiffnessIn this paper, the description of the shear strength of orthogonally reinforced concrete slabs without transverse reinforcement by the newly developed extended sandwich model is presented. Based on a sandwich model, the slab element is subdivided into two cover elements and a...

The current Korean Standard KDS 14 has adopted a strain-based shear strength model for evaluating the punching shear strength of slab–column connections reinforced with steel rebars. Thus, this study evaluated the applicability of the KDS 14 design model for slab–column connections reinforced with ...
In particular, the design safety of the RC transfer slab system is governed by the two-way shear strength (i.e., punching shear) at the shear transfer slab-column connection. When the two-way shear strength of the RC transfer slab is insufficient, shear reinforcement is generally used in ...
The test results from a series of six large scale members of which two were provided with headed shear studs, offer a direct evaluation of the full load-deformation behaviour of the specimens as well as the ultimate punching shear strength attained prior to failure at the critical slab ...
Punching shear failure constitutes a critical structural concern in conventional concrete slabs, prompting the development of various equations to determine their maximum shear strength. Voided concrete slabs have gained prominence for their ecological advantages and sustainability. However, the calculation of...

The punching strength and deformation capacity of slab-column connections is governing for design at ultimate limit state of flat slabs. This phenomenon has been investigated since decades with experimental programmes in an effort to derive empirical or mechanical design approaches. Such efforts, due to...
